CVE-2026-56706 Adminer before 5.4.3 CSRF Token Secret Recovery via XOR Masking

Adminer before 5.4.3 uses a CSRF token scheme that transmits both the XOR mask and the masked value in every token format rand XOR secret:rand, allowing anyone who observes a single CSRF token e.g., via network sniffing, log files, Referrer header, or XSS to recover the session secret with a sing...

CVE-2026-56706

Adminer before 5.4.3 contains a CSRF token design flaw: each token transmits both the XOR mask and the masked value in the format (rand XOR secret):rand, so a single observed token (via network sniffing, log files, Referrer header, or XSS) lets an attacker recover the session secret with one XOR ...
