CVE-2025-55580: SolidInvoice version 2.3.7 is vulnerable to a stored cross-site scripting (XSS) issue in the Clients module.

Noroxi assessment

Priority: Monitor (action score 21/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.26% (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: n/a n/a 2.3.8.

Low priority for now. Upgrade to n/a n/a 2.3.8 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

SolidInvoice version 2.3.7 is vulnerable to a stored cross-site scripting (XSS) issue in the Clients module. An authenticated attacker can inject JavaScript that executes in other users' browsers when the Clients page is viewed. The vulnerability is fixed in version 2.3.8.
