CVE-2024-1487: Photos and Files Contest Gallery < 21.3.1 - Author+ Stored Cross Site Scripting

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.39% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Unknown Photos and Files Contest Gallery 21.3.1.

Low priority for now. Upgrade to Unknown Photos and Files Contest Gallery 21.3.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The Photos and Files Contest Gallery WordPress plugin before 21.3.1 does not sanitize and escape some parameters, which could allow users with a role as low as author to perform Cross-Site Scripting attacks.
