Insufficient input sanitization and output escaping in the BlockArt Counter component allows an authenticated user with contributor\u2011level access or higher to inject arbitrary JavaScript into page attributes.

The flaw is not listed in CISA\u2019s KEV catalog.

Once the malicious script is stored, it executes automatically for any visitor who loads the affected page, leading to potential data theft or session hijacking."}}}}, "created": "2026-01-29T09:18:24.068157+00:00", "updated": "2026-04-20T16:00:10.646248+00:00", "vendors": ["wordpress", "wordpress$PRODUCT$wordpress", "wpblockart", "wpblockart$PRODUCT$blockart_blocks"]}
