CVE-2026-34236 HIGH PATCH GHSA This Week

Insufficient entropy in cookie encryption within Auth0 PHP SDK versions 8.0.0 through 8.18.x enables brute-force attacks against session cookie encryption keys, potentially allowing authenticated threat actors with network access to forge arbitrary session cookies and bypass authentication controls. Vendor-released patch available in version 8.19.0. No public exploit identified at time of analysis, though CVSS score of 8.2 reflects high severity due to potential for complete authentication bypass with cross-scope impact.

CVE-2025-0577 MEDIUM PATCH This Month

An insufficient entropy vulnerability was found in glibc. The getrandom and arc4random family of functions may return predictable randomness if these functions are called again after the fork, which happens concurrently with a call to any of these functions. [CVSS 4.8 MEDIUM]

CVE-2026-22698 HIGH POC PATCH This Week

SM2 elliptic curve implementations in RustCrypto versions 0.14.0-pre.0 and 0.14.0-rc.0 suffer from a critical entropy reduction flaw where ephemeral nonce generation requests only 32 bits instead of 256 bits of randomness, degrading encryption security from 128-bit to 16-bit strength. Public exploit code exists, allowing attackers to recover the nonce and decrypt ciphertexts using only the public key and encrypted message. A patch is available for affected deployments.
