Noroxi assessment

Priority: This week (action score 62/100)

  • CISA has confirmed exploitation in the wild (Feb 20, 2026). Remediation deadline for US federal agencies: Mar 13, 2026.
  • Probability of exploitation in the next 30 days: 26.8% (FIRST EPSS); higher than 98% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: Roundcube Webmail 1.5.12, 1.6.12.

Don’t wait for the next maintenance window. Upgrade to Roundcube Webmail 1.5.12, 1.6.12 or later.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Feb 20, 2026. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Mar 13, 2026.

This is a cross-site scripting (XSS) vulnerability. A well-configured Content-Security-Policy doesn't fix it, but greatly reduces its impact. Check your site's CSP and other security headers for free.
