CVE-2026-31889 Shopware has a potential take over of app credentials

Shopware is an open commerce platform. Prior to 6.6.10.15 and 6.7.8.1, a vulnerability in the Shopware app registration flow that could, under specific conditions, allow attackers to take over the communication channel between a shop and an app. The legacy app registration flow used HMAC‑based...

CVE-2026-31889

Shopware prior to versions 6.6.10.15 and 6.7.8.1 had a vulnerability in the app registration flow where the legacy HMAC‑based authentication did not sufficiently bind a shop installation to its domain. During re‑registration, the shop‑url could be updated without proving control of the previously...

CVE-2026-30223 OliveTin: JWT Audience Validation Bypass in Local Key and HMAC Modes

OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.11.1, when JWT authentication is configured using either "authJwtPubKeyPath" local RSA public key or "authJwtHmacSecret" HMAC secret, the configured audience value authJwtAud is not enforced during toke...

GHSA-XJHR-FM27-4HMX OpenFUN Richie Observable Timing Discrepancy in its sync_course_run_from_request function

An issue in OpenFUN Richie LMS in src/richie/apps/courses/api.py. The application used the non-constant time == operator for HMAC signature verification in the synccourserunfromrequest function. This allows remote attackers to forge valid signatures and bypass authentication by measuring response...

CVE-2025-68621

Trilium Notes has a timing-attack vulnerability in the sync authentication endpoint (/api/login/sync) affecting versions before 0.101.0. Unauthenticated remote attackers can recover HMAC hashes byte-by-byte via statistical timing analysis, enabling complete authentication bypass and full read/wri...

RustFS's RPC signature verification logs shared secret

Summary Invalid RPC signatures cause the server to log the shared HMAC secret and expected signature, which exposes the secret to log readers and enables forged RPC calls. Details In crates/ecstore/src/rpc/httpauth.rs:115-122 , the invalid signature branch logs sensitive data: rs if signature !=...

CVE-2013-10031

Versions of Plack-Middleware-Session before 0.17 for Perl are vulnerable to HMAC comparison timing attacks . This vulnerability is caused by incorrect comparison logic granularity, which could allow an attacker to deduce information through the time taken to perform comparisons. No specific explo...
