  • Probability of exploitation in the next 30 days: 0.15% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No special conditions are required; it is repeatable.
  • Fixed version: YesWiki yeswiki 4.6.7.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

YesWiki before 4.6.7 contains a cross-site request forgery vulnerability in the ajaxdeletepage handler, which permanently deletes a page on any GET request carrying a jsonp_callback parameter without checking a CSRF token. Attackers can lure a logged-in administrator or page owner to a crafted link to delete arbitrary pages along with their ACLs, links, triples, comments and referrers.

Root cause

State-changing requests rely on the session cookie the browser sends automatically; nothing verifies that the request came from the user’s own page.
