CVE-2026-67336 better-auth before 1.6.11 Insecure Cryptographic Defaults via oidcProvider
better-auth versions before 1.6.11 contain insecure cryptographic defaults in the oidcProvider and mcp plugins that advertise the none algorithm and accept plain PKCE by default. Attackers can exploit algorithm negotiation to accept unsigned tokens or intercept authorization codes when PKCE plain...

CVE-2026-67336
CVE-2026-67336 affects better-auth versions before 1.6.11, specifically the oidcProvider and mcp plugins. The root cause is insecure cryptographic defaults that advertise the none algorithm and allow plain PKCE by default. This can enable an attacker to exploit algorithm negotiation to accept uns...
CVE-2026-67335
Affected software: better-auth before 1.6.2. Vulnerability: OAuth state validation failure due to cookie-backed state storage without PKCE, allowing attackers to forge the state and supply an attacker-controlled authorization code. Impact: can create authenticated sessions bound to the attacker's...

droidground v1.0.11
DroidGround Website | Demo In traditional CTF challenges , it's common to hide flags in files on a system, requiring attackers to exploit vulnerabilities to retrieve them. However, in the Android world, this approach doesn't work well. APK files are easily downloadable and reversible, so placing ...
