CVE-2026-48082 1 Open-reception 1 Appointment-booking-software 2026-08-07 3.7 Low
OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.6, the bootstrap challenge endpoint at `/api/tenants/{id}/appointments/bootstrap-challenge` issues a SHA-256 proof-of-work with `difficulty=4` hex zeros, equivalent to 16 bits of work. Modern hardware solves this in under 200 milliseconds, providing essentially no friction against automated abuse of the patient booking flow. Proof-of-work is used in the booking flow as a rate-limiter for unauthenticated clients establishing tunnels and submitting appointments. At 16 bits of difficulty, the construct is decorative rather than effective. An attacker can solve PoW challenges as fast as the server can issue them, defeating the rate-limiting purpose. The handler also calls `challengeThrottleService.checkThrottle(binding, "passkey")`, but the binding includes attacker-controlled values (`tunnelId`, `clientPublicKey`, and optional `emailHash`). For each fresh attempt, the attacker can supply new values, producing a new throttle key and bypassing the per-binding accumulation. Practical abuse friction is therefore the PoW difficulty itself, not a stable per-IP or per-email server-side throttle. Version 1.0.6 fixes the issue.
CVE-2026-48083 1 Open-reception 1 Appointment-booking-software 2026-08-07 6.5 Medium
OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.2, the `/api/log` endpoint accepts unauthenticated POST requests, applies no schema validation to the message body, writes attacker-controlled content directly into the application's stdout log, interprets newline characters as real line breaks, and enforces no size or rate limits. Three independent abuse modes follow: log injection (forge log lines that look like legitimate system events), log volume DoS (saturate the logging pipeline at sustained 100+ requests per second of small messages), and oversized-payload submission (100 KB payloads accepted; larger sizes not tested). The most operationally damaging mode is log injection. An attacker can inject lines that an operator scanning logs would mistake for real system errors, mask their own activity behind fake noise, or pollute SIEM alerting rules with crafted false positives. A line such as `[error]: injected admin error` injected from an unauthenticated source is indistinguishable from the application's own error output once written to disk. Version 1.0.2 fixes the issue.
CVE-2026-48084 1 Open-reception 1 Appointment-booking-software 2026-08-07 7.4 High
OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Versions prior to 1.0.2 don't throttle failed passphrase login attempts. An attacker can submit unlimited wrong passphrase guesses against any known email address, capped only by the Argon2 verification cost (about 100 milliseconds per attempt on the tested host, giving 10 attempts per second sustained). The same backend implements a working per-account throttle on the WebAuthn challenge endpoint, which returns HTTP 429 after roughly 19 attempts. The passphrase branch simply does not invoke that throttle, leaving a supported high-value login path unprotected against credential stuffing and dictionary attacks. The asymmetry confirms this is an oversight rather than a design choice. The throttle infrastructure exists, is wired into the same auth backend, and works on the WebAuthn path. The passphrase branch in `/api/auth/login` was not updated to record failed attempts. Combined with the application's minimum-passphrase policy (12 characters, no entropy or dictionary checks), accounts using common base patterns such as `Spring2026!XX` or words from a leak corpus are realistically reachable in days on a single CPU, hours on a small GPU farm. Version 1.0.2 patches the issue.
CVE-2026-48087 1 Open-reception 1 Appointment-booking-software 2026-08-07 9.8 Critical
OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.2, the registration handler at `POST /api/auth/register/{userId}` validates the relationship between the WebAuthn challenge and the registration cookie's email but never validates that the `userId` in the URL belongs to that email. An unauthenticated attacker requests a challenge for their own email, generates a registration response with their own authenticator, and submits it against any victim user's URL. The challenge-vs-cookie email match passes, the WebAuthn ceremony validates, and `addPasskey` writes the attacker's credential into the victim's `user_passkey` rows. The next victim-email login accepts a passkey assertion from the attacker's authenticator and issues a session as the victim. User IDs are not strictly secret on this platform, but the exact set of exposure surfaces should be assessed by the maintainers. Staff-list endpoints return user IDs to authenticated tenant members per the route signature; live verification of all exposure surfaces (whether user IDs leak through any unauthenticated route, through invite-confirmation URLs, or through other administrative views) is part of the pending live PoC. Where the attacker knows the victim's email and userId, the analysis below becomes account takeover. Version 1.0.2 fixes the issue.
CVE-2026-48088 1 Open-reception 1 Appointment-booking-software 2026-08-07 9.4 Critical
OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.4, the route `POST /api/tenants/{tenantId}/staff/{staffId}/crypto` accepts and stores attacker-controlled ML-KEM-768 public keys against any tenant on the platform without authentication. The handler logs an "Unauthorized crypto key storage attempt" warning when neither a session nor a registration cookie is present, then proceeds to insert the row regardless. The platform's E2E claim that "even administrators cannot view sensitive information" is broken: any unauthenticated network attacker can register themselves as an additional encryption recipient for any tenant's future patient appointments. A second variant of the bug suppresses the unauthorized-warning log entry. The Zod schema makes the `email` field optional. When the request body omits `email` and the request carries no registration cookie, the comparison `registrationEmail === email` becomes `undefined === undefined`, which evaluates to `true`. The handler treats the request as a legitimate registration flow, skips the warning entirely, and stores the row. Successful storage is still recorded as an `[info]` log line, but the security-relevant warning that operators are most likely to monitor or alert on is gone. The `staff_crypto` table has no unique constraint on `user_id`, so an arbitrary number of attacker rows can coexist for the same staff identifier and all return as `is_active=true`. The supplied `staffId` does not need to match any existing user or pending invite. Schema validation on `passkeyId`, `publicKey`, and `privateKeyShare` is also weak: the literal string `<placeholder-base64>` was accepted, indicating no length, format, or cryptographic-validity check beyond field presence. This weakness is independent of the auth bypass but compounds it: a poisoned directory can also be filled with malformed entries that break legitimate booking flows. The injected key is consumed by the public booking flow. After completing the unauthenticated `bootstrap-challenge` and `bootstrap-verify` ceremony as a "patient", the resulting `bookingAccessToken` is accepted by `GET /api/tenants/{id}/appointments/staff-public-keys`, which returns the attacker-controlled keys alongside any legitimate ones. A new appointment encrypts its tunnel key with ML-KEM to all listed recipients, so the attacker becomes a co-recipient of the encryption and can decapsulate the tunnel key with the matching secret. From there, all appointment payloads for that booking are decryptable. Version 1.0.4 patches the issue.
CVE-2026-48054 1 Openzeppelin 1 Contracts-wizard 2026-08-07 8.8 High
OpenZeppelin Contracts Wizardis a web application to interactively build a contract out of components from OpenZeppelin Contracts. Versions prior to 0.10.9 generate a Hardhat test file (`test/test.ts`) by interpolating user-supplied `opts.name` (ERC20/ERC721) and `opts.uri` (ERC1155) directly into TypeScript string literals at `zip-hardhat.ts:48` and `:50` without any JavaScript string escaping. No authentication is required: an attacker crafts a URL such as `https[:]//wizard[.]openzeppelin[.]com/#/erc20?name=");require("child_process").execSync("...");("` and shares it with a developer. When the victim downloads the resulting zip archive and runs `npx hardhat test`, the injected Node.js code executes with the developer's local OS privileges. Version 0.10.9 fixes the issue.
CVE-2026-71554 1 Python-hyper 1 H2 2026-08-07 5.3 Medium
h2 is a pure-Python implementation of a HTTP/2 protocol stack. Versions up to and including 4.4.0 accept request header blocks containing more than one Host header, and forward every Host header to the consuming application. Where the consumer downgrades HTTP/2 to HTTP/1.1, the resulting request carries two Host header lines, providing a request smuggling primitive. This issue is fixed in version 4.4.1.
CVE-2026-71555 1 Thm-health 1 Pilos 2026-08-07 4.1 Medium
PILOS (Platform for Interactive Live-Online Seminars) is a frontend for BigBlueButton. From 2.1.0 until 4.14.1, PILOS does not send a Cross-Origin-Opener-Policy response header, so pages opened by PILOS via a link that opens a new browsing context (e.g., target="_blank") retain a window.opener reference back to the originating PILOS tab. A malicious destination page reached this way can use window.opener to navigate or manipulate the original PILOS tab, a technique known as reverse tabnabbing, potentially redirecting an authenticated user to a phishing page that mimics PILOS. This issue is fixed in version 4.14.1.
CVE-2026-62873 1 Microsoft 2 365 Admin Center, Windows Admin Center 2026-08-07 9.8 Critical
Improper verification of cryptographic signature in Microsoft 365 Admin Center allows an unauthorized attacker to elevate privileges over a network.
CVE-2026-11907 2 Wordpress, Xwp 2 Wordpress, Stream – Activity Log & Audit Trail 2026-08-07 6.5 Medium
The Stream plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.2.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to access all Stream activity records via the Heartbeat API.
CVE-2026-44950 1 Libxfonts2 1 Libxfont2 2026-08-07 7.5 High
A flaw was found in the libXfont2 font-server client. This heap buffer overflow vulnerability allows a malicious font server to send specially crafted glyph data. The fs_read_glyphs() function fails to properly validate the total size of the incoming data, leading to an overwrite of memory beyond the intended buffer. If the X server runs as a privileged user, this could result in privilege escalation, allowing an attacker to gain higher access. If the X server runs as an unprivileged user, it could lead to a denial of service, causing the system to crash.
CVE-2026-59679 1 Libxfont2 1 Libxfont2 2026-08-07 7.5 High
A flaw was found in the libXfont2 font-server client. A remote attacker, by operating a malicious font server, could exploit an out-of-bounds read/write vulnerability. This occurs because the client incorrectly handles font data, leading to an out-of-bounds memory access. This can lead to privilege escalation if the X server runs with root privileges, or a denial of service (crash) if it runs as an unprivileged user.
CVE-2026-66808 1 Hypershift 1 Addon Operator 2026-08-07 8.7 High
A flaw was found in hypershift-addon-operator. A hub-cluster administrator with write access to the hypershift-operator-install-flags ConfigMap can inject malicious command-line arguments into the privileged install Job. This vulnerability, known as argument injection, allows the attacker to pull arbitrary container images and gain full administrative control (cluster-admin code execution) on managed spoke clusters.
