CVE-2025-12177 is a vulnerability classified under CWE-321 (Use of Hard-coded Cryptographic Key) found in the codename065 Download Manager plugin for WordPress. The issue arises from the presence of a hardcoded Cron key used to authenticate execution of two critical cron job functions: deleteExpired() and clearTempDataCPCron(). These functions are responsible for deleting expired posts and clearing temporary cache data, respectively. Because the key is hardcoded and publicly known or easily guessable, unauthenticated attackers can invoke these cron jobs remotely without any authentication or user interaction. This unauthorized triggering can lead to unintended deletion of content and cache clearing, impacting data integrity and potentially disrupting normal site operations. The vulnerability affects all versions up to and including 3.3.30 of the plugin. The CVSS v3.1 base score is 5.3, reflecting a medium severity with network attack vector, low attack complexity, no privileges or user interaction required, and impact limited to integrity. No patches or exploit code are currently publicly available, but the risk remains due to the ease of exploitation. The flaw is significant because it undermines the trustworthiness of content management on affected WordPress sites, which are widely used across various sectors.

For European organizations, this vulnerability poses a risk primarily to the integrity of web content and cached data managed by the Download Manager plugin. Unauthorized deletion of expired posts could lead to loss of important archival content or disrupt workflows that depend on these posts. Clearing cache unexpectedly may degrade user experience or cause temporary service disruptions. While confidentiality and availability are not directly impacted, the integrity compromise can affect business operations, brand reputation, and user trust. Organizations in sectors such as e-commerce, media, education, and government that rely heavily on WordPress for content delivery are particularly vulnerable. The ease of exploitation without authentication increases the threat level, especially for publicly accessible websites. Although no known exploits are reported yet, the presence of a hardcoded key makes it a likely target for opportunistic attackers. European entities with compliance obligations around data integrity and operational continuity should prioritize addressing this vulnerability.

Immediate mitigation should focus on restricting access to the vulnerable cron job endpoints by implementing web application firewall (WAF) rules that block unauthorized requests targeting the deleteExpired() and clearTempDataCPCron() functions. Network-level controls such as IP whitelisting or VPN access for cron job execution can reduce exposure. Administrators should monitor logs for unusual invocations of these cron jobs to detect potential exploitation attempts. Since no official patch is currently available, consider disabling or removing the Download Manager plugin temporarily if feasible. Alternatively, custom code modifications to remove or replace the hardcoded key with a securely generated, configurable secret can mitigate the risk. Regularly update WordPress and all plugins once a vendor patch is released. Additionally, implement routine backups of website content and cache data to enable recovery from unauthorized deletions. Educate site administrators about this vulnerability and encourage vigilance in monitoring site integrity.
