Noroxi assessment

Priority: This week (action score 66/100)

  • CISA has confirmed exploitation in the wild (Oct 20, 2025). Remediation deadline for US federal agencies: Nov 10, 2025.
  • Probability of exploitation in the next 30 days: 3.2% (FIRST EPSS); higher than 88.1% 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: webkit2gtk (Debian:11) 2.38.0-1~deb11u1; wpewebkit (Debian:11) 2.38.0-1~deb11u1; webkit2gtk (Debian:12) 2.38.0-1.

Don’t wait for the next maintenance window. Upgrade to webkit2gtk (Debian:11) 2.38.0-1~deb11u1; wpewebkit (Debian:11) 2.38.0-1~deb11u1; webkit2gtk (Debian:12) 2.38.0-1 or later.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
