CVE-2026-45675 Open WebUI: LDAP and OAuth First-User Race Condition Allows Multiple Admin Accounts

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, the LDAP and OAuth authentication flows use a TOCTOU Time-of-Check-Time-of-Use pattern for first-user admin role assignment. The regular signup handler signuphandler in auths.py, lin...

Gitsign is a keyless Sigstore to signing tool for Git commits with your a GitHub / OIDC identity. From 0.4.0 to before 0.15.0, CertVerifier.Verify in pkg/git/verifier.go unconditionally dereferences certs0 after sd.GetCertificates without checking the slice length. A CMS/PKCS7 signed message with...

Four OpenClaw Flaws Enable Data Theft, Privilege Escalation, and Persistence

Cybersecurity researchers have disclosed a set of four security flaws in OpenClaw that could be chained to achieve data theft, privilege escalation, and persistence. The vulnerabilities, collectively dubbed Claw Chain by Cyera, can permit an attacker to establish a foothold, expose sensitive data...

CVE-2026-43324

A flaw was found in the Linux kernel's dummy-hcd driver. This vulnerability stems from an interrupt synchronization error where emulated interrupts can occur after the system attempts to synchronize interrupt handlers. This timing issue creates a race condition, potentially allowing a callback...

BIT-GRAFANA-2026-28379 Viewer-triggered race condition in Grafana Live leads to complete server crash

A race condition in Grafana Live allows authenticated users with Viewer role to trigger a server crash by sending concurrent requests that cause a fatal map access error. This results in complete service unavailability requiring restart of the Grafana server...
