CVE-2026-63384 1 Libevent Project 1 Libevent 2026-08-21 N/A
Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has an incorrect integer conversion in event_tagging.c when evtag_unmarshal_header uses evtag_decode_int to decode an attacker-controlled uint32 payload length and returns it as a signed int. Values above INT_MAX become negative or truncated, and evtag_unmarshal_string can use the converted value in allocation sizing, producing a wrapped large allocation request and denial of service. This issue is fixed in versions 2.1.13 and 2.2.2-alpha.
CVE-2026-63387 1 Libevent Project 1 Libevent 2026-08-21 7 High
Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has an off-by-one stack buffer overflow in evdns.c when dnsname_to_labels formats a name-bearing DNS record at the end of the 64 KB stack buffer allocated by evdns_server_request_format_response. The final-label check permits j plus label_len plus one to equal buf_len, after which the terminating null byte is written to buf[buf_len]. A crafted DNS server response containing PTR, CNAME, MX, NS, or SOA data can trigger the one-byte out-of-bounds write and crash or corrupt the process. This issue is fixed in versions 2.1.13 and 2.2.2-alpha.
CVE-2026-63379 1 Libevent Project 1 Libevent 2026-08-21 N/A
Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent processes chunked HTTP trailers in http.c through evhttp_read_trailer and merges them into request headers. The fix introduces evhttp_parse_headers_impl_ and a temporary trailer header list. An unauthenticated remote attacker can place security-sensitive fields in trailers so that an upstream proxy and the libevent application interpret different effective headers, enabling header smuggling, authorization bypass, proxy-header spoofing, or cache poisoning. The fix parses trailers into a temporary header list and discards them instead of merging them into req->input_headers. This issue is fixed in versions 2.1.13 and 2.2.2-alpha.
CVE-2026-63385 1 Libevent Project 1 Libevent 2026-08-21 N/A
Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has two HTTP parsing weaknesses in http.c. evhttp_decode_uri_internal decodes percent-encoded %00 bytes into literal NUL characters, which can cause downstream C string operations to truncate a path and bypass validation performed on a different representation. evhttp_header_is_valid_value also accepts obsolete line folding in header values containing carriage return or line feed characters, allowing a proxy and libevent to interpret headers differently and enabling header injection or access control bypass. The CRLF header acceptance is fixed in versions 2.1.13 and 2.2.2-alpha, but the reviewed patches do not clearly remediate the URI NUL-truncation condition.
CVE-2026-66785 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-21 9.9 Critical
A flaw was found in Submariner. This vulnerability allows a malicious cluster (spoke) to redirect network traffic from other connected clusters (peer clusters) by publishing a specially crafted network endpoint. The system fails to properly validate the network subnets provided by the malicious cluster, enabling it to declare arbitrary network ranges. Consequently, all network traffic intended for these arbitrary ranges from peer clusters will be rerouted through the attacker's tunnel, potentially leading to unauthorized information disclosure or network disruption.
CVE-2026-66787 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-21 8.7 High
A flaw was found in the lighthouse component of Red Hat Advanced Cluster Management for Kubernetes. This vulnerability stems from insufficient validation of advertised IP addresses within EndpointSlice objects. A compromised spoke cluster can exploit this by creating EndpointSlices with attacker-controlled IP addresses, causing other clusters' lighthouse DNS to redirect legitimate service traffic to malicious endpoints. This enables a remote attacker to conduct transparent Man-in-the-Middle (MITM) attacks on cross-cluster service communications, potentially leading to unauthorized information disclosure and data manipulation.
CVE-2026-15743 1 Perl-catalyst 1 Catalyst Plugin Static Simple 2026-08-21 N/A
Catalyst::Plugin::Static::Simple versions through 0.38 for Perl mark responses as publicly cacheable. The _serve_static method always sets the Cache-Control header to "public", with no means of overriding it. This advises proxies that the content may be stored in a shared cache, and may be reused in responses to requests from other users. (This includes requests with an Authorization header.) Configuring the expires time to "0" to disable caching, as documented, is ignored.
CVE-2026-66788 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-21 9.9 Critical
A flaw was found in Lighthouse. A remote attacker, by compromising a spoke cluster, can exploit a vulnerability where the destination namespace for resource injection is derived from an attacker-controlled label or annotation on the broker object. This allows the attacker to inject unauthorized EndpointSlices and ServiceImports into any namespace on peer clusters, including critical system namespaces like kube-system and openshift-*. This could lead to privilege escalation or other forms of system compromise within the cluster.
CVE-2026-72854 1 Msgpack 1 Msgpack 2026-08-21 5.3 Medium
msgpack_unpacker_expand_buffer in src/unpack.c, reached through the public msgpack_unpacker_reserve_buffer API, computes its new buffer size using an unchecked size_t addition of the requested size and the amount already used. The doubling loop guards its own multiplication against overflow, but the addition in the loop condition is unguarded, so a request near SIZE_MAX wraps: the loop condition is already satisfied, the allocation is performed at the small pre-wrap size, and the function returns true. The caller is told the requested capacity was reserved when it was not, so a subsequent write of the requested length overflows the heap buffer. The library's own example/lib_buffer_unpack.c demonstrates the reserve-then-write pattern, and its defensive assert comparing capacity against the request is compiled out under NDEBUG. msgpack-c's own decode entry points do not derive the reservation size from untrusted input, so reaching this requires an integration that passes an attacker-influenced length to the reservation API, such as a length-prefixed streaming transport.
CVE-2026-75514 1 Bunkerity 1 Bunker Web 2026-08-21 5.9 Medium
BunkerWeb is an open-source, next-generation Web Application Firewall. Prior to 1.6.13, the blacklist, greylist, and antibot modules in src/common/core/blacklist/blacklist.lua, src/common/core/greylist/greylist.lua, and src/common/core/antibot/antibot.lua trust PTR suffix matches in IGNORE_RDNS, GREYLIST_RDNS, and ANTIBOT_IGNORE_RDNS without using get_ips to confirm that the hostname resolves to the client address. An unauthenticated remote attacker who controls a PTR record can spoof a trusted suffix to bypass rDNS-based blacklisting, gain greylist treatment, or skip an antibot challenge. This issue is fixed in version 1.6.13.
CVE-2026-19586 2 Tp-link, Tp-link Systems Inc 19 Dr3150 V1, Dr3220v-4g V1, Dr3650v-4g V1 and 16 more 2026-08-21 N/A
A pre-authentication OS command injection vulnerability has been identified in Omada gateways configured to operate as an OpenVPN Server due to insufficient validation of client-supplied data during OpenVPN connection establishment. An unauthenticated remote attacker may provide specially crafted input influencing backend command execution logic before authentication completes. Exploitation requires the OpenVPN Server feature to be enabled, VPN service reachable by the attacker and attacker to be able to initiate an OpenVPN connection attempt.  Successful exploitation may allow arbitrary command execution, potentially leading to full compromise of the affected device.
CVE-2026-43678 1 Apple 1 Swiftnio 2026-08-21 5.3 Medium
An unauthenticated remote peer can crash any NIOWebSocket-based server (including Vapor and Hummingbird) with a single 11-byte frame sent after a completed WebSocket handshake, dropping all active connections until the process restarts. This vulnerability is addressed in swift-nio version 2.101.0.
CVE-2026-67567 1 Redhat 2 Acm, Advanced Cluster Management For Kubernetes 2026-08-21 9.9 Critical
A flaw was found in the multicloud-operators-subscription component. This vulnerability allows a tenant, who has the ability to create HelmRelease custom resources (CRs), to bypass existing security controls. The system's HelmRelease controller processes Helm chart templates using its own elevated ServiceAccount privileges without proper validation. This enables the tenant to deploy arbitrary resources across the entire cluster, leading to a significant security compromise.
CVE-2026-43798 1 Apple 1 Swiftnio Ssh 2026-08-21 N/A
A single crafted SSH message gives an unauthenticated network attacker an out-of-bounds stack write of attacker-controlled length and content against any application built on swift-nio-ssh. This vulnerability is addressed in swift-nio-ssh version 0.14.1.
CVE-2026-70105 1 Microsoft 12 365 Apps, Microsoft 365 Apps For Enterprise, Microsoft Office Ltsc For Mac 2021 and 9 more 2026-08-21 6.5 Medium
Improper input validation in Microsoft Office Word allows an unauthorized attacker to disclose information over a network.
CVE-2026-72843 1 Evershop 1 Evershop 2026-08-21 9.8 Critical
The customer update route in EverShop is declared with "access": "public" in packages/evershop/src/modules/customer/api/updateCustomer/route.json, which causes the admin authentication middleware to call next() without checking the caller, and no customer-session middleware guards the route; the only middleware in the chain parses the JSON body. The handler in updateCustomer.js then loads the customer by the uuid taken from the URL path and writes the supplied fields back to that record, hashing a password if one is provided, without verifying that the caller owns the record. An unauthenticated request carrying a known customer uuid can therefore overwrite that customer's email address and password and read back the updated record from the 200 response, taking over the account and locking out its owner. Customer uuids are exposed through order confirmation email links and administrative URLs. Version 2.2.1 changes the route to "access": "private".
CVE-2026-16520 1 Genians 2 Genian Nac, Genian Ztna 2026-08-21 N/A
Improper input validation and Exposure of sensitive information through data queries vulnerability in Genians Genian NAC V4.0, Genians Genian NAC V5.0, and Genians Genian ZTNA V6.0 allows SQL Injection and Authentication Bypass. This issue affects Genian NAC V4.0: from 4.0.0 before 4.0.175(Revision 150340); Genian NAC V5.0: from 5.0.0 before 5.0.65 LTS(Revision 150331), from 5.0.0 before 5.0.75 LTS(Revision 150330), from 5.0.0 before 5.0.87 Release Stable(Revision 150329), and from 5.0.0 before 5.0.88(Revision 150328); Genian ZTNA V6.0: from 6.0.0 before 6.0.26 LTS(Revision 150337), from 6.0.0 before 6.0.35 LTS(Revision 150336), from 6.0.0 before 6.0.47 Release Stable(Revision 150334), and from 6.0.0 before 6.0.48(Revision 150333).
CVE-2026-45199 1 Imaginationtech 1 Graphics Ddk 2026-08-21 N/A
Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory. Software installed and run under a Guest VM can send commands to the GPU which result in out of bounds memory accesses. These can be used to escalate privileges.
CVE-2026-45201 1 Imaginationtech 1 Graphics Ddk 2026-08-21 N/A
Software installed and run as a non-privileged user may conduct improper GPU system calls to pass invalid log2 page size when allocating physical pages leading to OOB read and/or write due to improper validation of the said value. Such crafted log2 page size could lead to 4K pages being treated as higher order pages and allowing read and/or write access to the memory beyond 4K threshold.
CVE-2026-45202 1 Imaginationtech 1 Graphics Ddk 2026-08-21 N/A
Software installed and run as a non-privileged user may conduct GPU system calls which cause GPU memory leaks and possible kernel heap corruption. Scenario caused by memory free paths not maintaining state data of upgraded higher order allocations. This could cause memory leak or double free event.
