YesWiki before 4.6.7 contains a cross-site request forgery vulnerability in the admintag action that allows attackers to delete tag associations by luring administrators to crafted GET links. Attackers can supply a wide id range in the delete_tag parameter via top-level navigation, carrying the SameSite=Lax admin cookie, to bulk-delete tag triples.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
