Noroxi assessment

Priority: This week (action score 65/100)

  • CISA has confirmed exploitation in the wild (Nov 10, 2026). Remediation deadline for US federal agencies: Nov 24, 2026.
  • Probability of exploitation in the next 30 days: 0.96% (FIRST EPSS); higher than 62% 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.
  • Fixed version: libxslt (Alpine:v3.21) 1.1.42-r3; libxslt (Alpine:v3.22) 1.1.43-r4; chromium (openSUSE:Tumbleweed) 157.0.8103.50-1.1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Upgrade to libxslt (Alpine:v3.21) 1.1.42-r3; libxslt (Alpine:v3.22) 1.1.43-r4; chromium (openSUSE:Tumbleweed) 157.0.8103.50-1.1 or later.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Nov 10, 2026. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Nov 24, 2026.
