PYSEC-2026-3475 LightRAG is Vulnerable to Authentication Bypass: hardcoded DEFAULT_TOKEN_SECRET and public /auth-status defeat LIGHTRAG_API_KEY protection

Summary When LightRAG is deployed with LIGHTRAGAPIKEY set but AUTHACCOUNTS unset an officially documented "API-Key authentication" mode, the X-API-Key protection can be bypassed by any remote unauthenticated attacker. The bypass does not require network contact with the victim server — an attacke...

Cacti 1.2.24 - SQL Injection

Cacti is an open source operational monitoring and fault management framework. Affected versions are subject to a SQL injection discovered in graphview.php. Since guest users can access graphview.php without authentication by default, if guest users are being utilized in an enabled state, there...

kernel: KVM: x86: Fix shadow paging use-after-free due to unexpected role

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM x86 shadow paging mechanism. This vulnerability occurs when a host page directory entry PDE mapping is changed from within the guest, leading to an unexpected role mismatch in shadow paging. This mismatch can cause a...

CVE-2026-63940

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM Secure Encrypted Virtualization SEV module. This vulnerability occurs because the system does not properly handle Port I/O requests with a length of zero. An attacker, potentially from a guest virtual machine, could exploit...

CVE-2026-63938

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM Secure Encrypted Virtualization SEV feature. When processing Page State Change PSC requests, the system does not properly validate the PSC buffer against the effective size of the scratch area. This can occur if a guest...

CVE-2026-63937

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM with Secure Encrypted Virtualization SEV. This time-of-check to time-of-use TOCTOU vulnerability exists when KVM processes the guest-accessible Page State Change PSC buffer. A misbehaving guest could exploit this timing issue...
