CVE-2025-7828 is a vulnerability identified in the WP Filter & Combine RSS Feeds plugin for WordPress, developed by evigeo. The issue stems from a missing authorization check (CWE-862) in the post_listing_page() function, which is responsible for managing RSS feed listings within the plugin. This missing capability check means that any authenticated user with Contributor-level access or higher can invoke this function to delete RSS feeds without proper permission validation. Since Contributors typically have limited publishing rights but not administrative control, this flaw elevates their ability to modify plugin data beyond intended boundaries. The vulnerability affects all versions up to and including 0.4 of the plugin. The CVSS v3.1 base score is 4.3 (medium), reflecting that the attack vector is network-based (remote), requires low attack complexity, and privileges at the Contributor level, but does not require user interaction. The impact is limited to integrity, as attackers can delete feeds, but confidentiality and availability remain unaffected. No known exploits have been reported in the wild, and no official patches have been published yet. The vulnerability was publicly disclosed on August 23, 2025, with the initial reservation date on July 18, 2025. The plugin is used within WordPress environments, which are widely deployed globally, making this a relevant concern for many organizations running WordPress sites with this plugin installed.

The primary impact of CVE-2025-7828 is unauthorized modification of RSS feed data within affected WordPress sites. Attackers with Contributor-level access can delete feeds, potentially disrupting content aggregation or syndication workflows. While this does not directly compromise site confidentiality or availability, it undermines data integrity and could lead to content loss or manipulation. For organizations relying on these feeds for critical content delivery or marketing, this could degrade user experience and trust. Additionally, if attackers combine this vulnerability with other flaws or social engineering, they might escalate privileges or cause further damage. Since the vulnerability requires authenticated access at Contributor level or above, the risk is mitigated somewhat by proper user role management. However, in environments with many contributors or weak access controls, the threat is more significant. The lack of patches and public exploits means immediate widespread exploitation is unlikely, but the vulnerability should be addressed promptly to prevent future attacks.

To mitigate CVE-2025-7828, organizations should first restrict Contributor-level access to trusted users only, minimizing the risk of unauthorized feed deletion. Site administrators should audit user roles and permissions regularly to ensure least privilege principles are enforced. Until an official patch is released, consider disabling or uninstalling the WP Filter & Combine RSS Feeds plugin if it is not essential. If the plugin is critical, monitor logs for unusual feed deletion activities and implement alerting mechanisms. Applying Web Application Firewall (WAF) rules to detect and block suspicious requests targeting the post_listing_page() function may provide temporary protection. Additionally, consider implementing custom capability checks or code patches if feasible, to enforce authorization on the vulnerable function. Regular backups of WordPress content and feeds are recommended to enable recovery in case of data loss. Stay updated with vendor advisories for any forthcoming patches and apply them promptly once available.
