AI Analysis
Technical Summary
CVE-2026-7796 is a stored cross-site scripting vulnerability in the EmbedPress WordPress plugin (versions up to 4.5.3). It occurs due to improper neutralization of input in the 'url' attribute of a block, enabling authenticated users with contributor or higher privileges to inject arbitrary web scripts. These scripts execute in the context of users viewing the compromised pages, potentially leading to information disclosure or session hijacking. The vulnerability is classified under CWE-79 and has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N). No vendor patch or official remediation has been documented as of the published date.
Potential Impact
The vulnerability allows authenticated attackers with contributor-level access or higher to inject persistent malicious scripts into pages via the 'url' attribute. When other users access these pages, the injected scripts execute in their browsers, potentially leading to limited confidentiality and integrity impacts such as theft of user credentials or unauthorized actions performed on behalf of users. Availability is not affected. The scope is changed (S:C) indicating that the vulnerability affects resources beyond the attacker’s privileges.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the EmbedPress plugin if possible. Monitor for plugin updates from the vendor and apply them promptly once released.
