CVE-2026-42678Network attack vector

Unauthenticated browser script execution via undisclosed DOM handling

Published Jun 1, 2026 · Updated Jun 1, 2026

DOM-based cross-site scripting in StellarWP GiveWP 4.14.5 and earlier allows remote attackers to execute script in a user's browser. The public CNA record identifies DOM-based XSS but does not disclose the affected script, attacker-controlled DOM source, or unsafe sink. Exploitation requires no account but does require a user to open attacker-influenced content, after which script runs in that user's site origin.
