CVE-2026-1931 is a stored cross-site scripting vulnerability in the Rent Fetch plugin for WordPress, affecting all versions up to and including 0.32.4. The issue stems from insufficient sanitization and escaping of user-supplied input in the 'keyword' parameter, enabling unauthenticated attackers to inject arbitrary web scripts. These scripts execute in the context of users visiting the injected pages, potentially leading to session hijacking or other client-side impacts. The vulnerability has a CVSS 3.1 base score of 7.2, reflecting network attack vector, low attack complexity, no privileges required, no user interaction, and impacts on confidentiality and integrity with scope changed.

Successful exploitation allows unauthenticated attackers to inject and execute arbitrary scripts in users' browsers when they access affected pages, potentially compromising user confidentiality and integrity. There is no impact on availability. No known exploits are currently reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling or removing the Rent Fetch plugin or applying manual input sanitization and output escaping if feasible. Monitor vendor channels for updates and patches addressing this vulnerability.
