CVE-2025-62954 identifies a missing authorization vulnerability in the Codeinwp Revive Old Posts WordPress plugin, specifically in the tweet-old-post functionality. The vulnerability arises from incorrectly configured access control security levels, which fail to properly verify whether a user has the necessary permissions to perform certain actions within the plugin. This can allow an attacker, potentially even an unauthenticated user depending on the site configuration, to exploit the plugin to execute unauthorized operations such as posting tweets or manipulating scheduled social media posts. The affected versions include all releases up to and including 9.3.3. The plugin is widely used to automate the sharing of older blog posts on social media platforms, making it a valuable tool for digital marketing. The lack of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed, but the missing authorization nature suggests a significant security gap. No patches or known exploits are currently documented, but the vulnerability's presence in a popular plugin increases the risk of future exploitation. Attackers exploiting this flaw could disrupt social media campaigns, post unauthorized content, or potentially leverage the plugin as a pivot point for further compromise within the WordPress environment.

For European organizations, especially those heavily reliant on WordPress for content management and digital marketing, this vulnerability poses a risk to the integrity and availability of their social media presence. Unauthorized posting could damage brand reputation, spread misinformation, or lead to account suspensions by social media providers. Additionally, exploitation could serve as an entry point for attackers to escalate privileges or deploy further attacks within the WordPress site, potentially compromising sensitive data or disrupting business operations. Organizations in sectors such as media, e-commerce, and public services that use automated social media tools are particularly vulnerable. The impact extends beyond direct content manipulation, as trust in automated marketing workflows could be undermined. Given the plugin’s popularity, a large number of European websites could be affected, increasing the potential scale of impact.

Immediate mitigation steps include restricting access to the Revive Old Posts plugin functionality to trusted administrators only, using WordPress role and capability management to limit who can interact with the plugin. Employing web application firewalls (WAFs) to monitor and block suspicious requests targeting the plugin endpoints can reduce exploitation risk. Organizations should monitor for updates from Codeinwp and apply patches promptly once released. In the interim, disabling the plugin or its vulnerable features may be necessary for high-risk environments. Conducting regular audits of user permissions and plugin configurations can help identify and remediate insecure settings. Additionally, monitoring social media accounts for unauthorized posts and enabling multi-factor authentication on linked social media accounts can mitigate downstream impacts. Finally, maintaining comprehensive backups and incident response plans will aid recovery if exploitation occurs.
