CVE-2024-48311 is a Cross-Site Request Forgery (CSRF) vulnerability identified in Piwigo version 14.5.0, specifically targeting the Edit album function. CSRF vulnerabilities allow attackers to induce authenticated users to submit unauthorized requests to a web application, leveraging the victim’s active session and privileges. In this case, the vulnerability permits an attacker to craft malicious web requests that, when visited by an authenticated user, can modify album data without the user’s consent or knowledge. The CVSS 3.1 base score of 8.8 reflects the vulnerability’s high impact and ease of exploitation: it requires no privileges (PR:N), no physical or local access (AV:N), and only user interaction (UI:R), but can result in complete compromise of confidentiality, integrity, and availability (C:H/I:H/A:H). The scope remains unchanged (S:U), meaning the impact is confined to the vulnerable component. No patches have been released at the time of publication, and no exploits are known to be active in the wild. The vulnerability is classified under CWE-352, which covers CSRF attacks. Given Piwigo’s role as a web-based photo gallery management system, exploitation could lead to unauthorized album edits, data tampering, or deletion, severely impacting user trust and data integrity.

The impact of CVE-2024-48311 is significant for organizations using Piwigo 14.5.0 to manage digital photo galleries. Successful exploitation can lead to unauthorized modification or deletion of album data, resulting in loss of data integrity and availability. Confidentiality may also be compromised if attackers manipulate album metadata or access controls. Since the vulnerability requires only user interaction and no elevated privileges, attackers can leverage social engineering to trick users into executing malicious requests. This can disrupt business operations, damage reputations, and cause data loss. Organizations relying on Piwigo for public-facing or internal photo management services are at risk of service disruption and potential data breaches. The absence of known exploits in the wild provides a window for proactive mitigation, but the high CVSS score indicates that the vulnerability should be treated with urgency.

To mitigate CVE-2024-48311, organizations should immediately implement the following measures: 1) Disable or restrict access to the Edit album functionality until a vendor patch is available. 2) Implement anti-CSRF tokens in all state-changing requests to ensure that requests originate from legitimate users. 3) Enforce strict SameSite cookie attributes to reduce CSRF attack vectors. 4) Educate users about the risks of clicking on suspicious links and the importance of logging out from Piwigo sessions when not in use. 5) Monitor web server and application logs for unusual or unauthorized album edit requests. 6) If possible, deploy Web Application Firewalls (WAFs) with rules to detect and block CSRF attack patterns targeting Piwigo endpoints. 7) Stay updated with vendor advisories and apply official patches promptly once released. These steps go beyond generic advice by focusing on immediate functional restrictions, user awareness, and layered defenses tailored to the vulnerability’s nature.
