CVE-2025-8517: givanz Vvveb session fixiation

Noroxi assessment

Priority: Monitor (action score 9/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.3% (FIRST EPSS); higher than 83.4% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: givanz Vvveb 1.0.7.
  • Severity is disputed: the assigning authority (CNA) scores it 5.3, NVD 2.1.

Low priority for now. Upgrade to givanz Vvveb 1.0.7 or later.
