CVE-2025-26965 identifies an authorization bypass vulnerability in the Amelia booking plugin, a popular WordPress booking system used for appointment and event scheduling. The vulnerability stems from incorrectly configured access control security levels that rely on user-controlled keys. Attackers can exploit this flaw by manipulating these keys to bypass authorization mechanisms, granting them unauthorized access to restricted areas or functions within the Amelia system. This could include viewing, modifying, or deleting booking data or administrative settings without proper permissions. The affected versions include all releases up to and including version 1.2.16. Although no public exploits have been reported, the nature of the vulnerability suggests it could be exploited remotely if the plugin is accessible via the web. The lack of a CVSS score means severity must be assessed based on impact and exploitability factors. Given that authorization bypass can lead to significant confidentiality and integrity breaches, and that exploitation does not require user interaction or complex prerequisites, the threat is substantial. The vulnerability was published on February 25, 2025, and assigned by Patchstack. No official patches or mitigations are linked yet, indicating the need for vigilance and proactive security measures by users of the Amelia plugin.

The primary impact of CVE-2025-26965 is unauthorized access to sensitive booking and administrative data within the Amelia plugin environment. This can lead to data breaches, manipulation of booking records, unauthorized changes to scheduling, and potential disruption of business operations relying on the booking system. For organizations, this could translate into loss of customer trust, regulatory compliance violations (especially where personal data is involved), and financial losses due to operational downtime or fraud. Since the vulnerability allows bypassing authorization controls, attackers could escalate privileges or impersonate legitimate users, increasing the risk of further compromise. The scope includes any organization using vulnerable versions of Amelia, particularly those in service industries such as healthcare, education, hospitality, and professional services where appointment scheduling is critical. The absence of known exploits in the wild currently limits immediate widespread impact, but the vulnerability’s presence in a widely used plugin makes it a high-value target for attackers once exploit code becomes available.

To mitigate CVE-2025-26965, organizations should immediately audit their use of the Amelia plugin and identify if they are running affected versions (up to 1.2.16). Until an official patch is released, consider disabling the plugin or restricting access to its administrative interfaces via network controls such as IP whitelisting or VPN access. Review and tighten access control configurations within the plugin and WordPress environment to minimize exposure. Monitor logs for unusual access patterns or unauthorized attempts to manipulate booking data. Engage with the vendor or Patchstack for updates on patches or security advisories. Additionally, implement web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin’s endpoints. Educate administrators on the risks of user-controlled keys and enforce the principle of least privilege for all users interacting with the booking system. Regularly back up booking data to enable recovery in case of compromise.
