Public exploitAvailablePublished on Exploit-DB

The fopen function in PHP 5.2.0 does not properly handle invalid URI handlers, which allows context-dependent attackers to bypass safe_mode restrictions and read arbitrary files via a file path specified with an invalid URI, as demonstrated via the srpath URI.

CVSS

Base score: 10
Version: 2.0
Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 7.11 %
Percentile among all scored CVEs: 94
Score date: 10/23/2026

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.
