The vulnerability arises from the plugin\u2019s failure to neutralize user input during page rendering, a classic input validation weakness identified as CWE\u201179. If exploited, a malicious payload could steal credentials, hijack sessions, deface the site, or execute arbitrary client\u2011side actions, compromising the confidentiality and integrity of the user\u2019s browser environment.", "risk_and_exploitability": "With a CVSS score of 6.5 the vulnerability is considered moderate in severity, while an EPSS score of less than 1% indicates that it is unlikely to be frequently exploited in the wild. The flaw is not listed in the CISA KEV catalog. The attack requires user interaction with a victim\u2019s browser, typically via a crafted link or embedded content that triggers the plugin\u2019s processing of unsanitized input. As it is a DOM\u2011based exploitation, the attacker needs the victim to load the insecure page in order to trigger the malicious script."}}}}, "created": "2026-04-08T19:28:08.529480+00:00", "updated": "2026-04-14T16:38:44.850075+00:00", "vendors": ["vladimir_prelovac", "vladimir_prelovac$PRODUCT$seo_friendly_images", "wordpress", "wordpress$PRODUCT$wordpress"]}
