  • Probability of exploitation in the next 30 days: 0.31% (FIRST EPSS).
  • 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: n/a n/a 2.0.20.

Low priority for now. Upgrade to n/a n/a 2.0.20 or later.
