CVE-2023-26876: SQL injection vulnerability found in Piwigo v.13.5.0 and before allows a remote attacker to execute arbitrary code via the filter_user_id pa

Noroxi assessment

Priority: Plan (action score 40/100)

A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
Because a ready-made attack tool exists, priority is at least “Plan”.
Probability of exploitation in the next 30 days: 9.7% (FIRST EPSS); higher than 95.5% of all records.
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.
