Status: ModifiedCritical (9.8)—💥 Exploit

Session fixation vulnerability in Apache2Triad 1.5.4 allows remote attackers to hijack web sessions via the PHPSESSID parameter.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
