When Consent Outlives Context: Residual Authority Replay in Long-Lived Agents

LLM agents increasingly rely on user approval to authorize security-sensitive actions at runtime. Such approvals are granted within a specific task and execution context. In long-lived agents, authorization decisions may need to persist across tasks or sessions. We find that this continuity can...

CVE-2026-100635

Versions of SiYuan prior to v3.8.4 are susceptible to an authentication bypass vulnerability within the publish service . The root cause is that session cookies are issued without Secure or SameSite attributes over plaintext HTTP connections. This allows an on-path attacker to intercept a valid p...

FreeBSD : p5-Authen-SASL -- Replay attack in Authen::SASL::Perl::DIGEST_MD5 (023a3d0c-b987-11f1-ad2b-40b034429ecf)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 023a3d0c-b987-11f1-ad2b-40b034429ecf advisory. Authen-SASL project reports: Authen::SASL::Perl::DIGESTMD5 versions before 2.2100 for Perl accept...

CVE-2026-79313

A flaw was found in webpy. The application's session management relies on periodic cleanup to expire sessions instead of checking the last-access time when a session is loaded. This allows an attacker holding a previously valid session cookie to replay and use an expired session. As a result, an...
