CVE-2025-58988 is a Stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the Joe Dolson My Tickets product up to version 2.0.22. Stored XSS occurs when malicious input is improperly neutralized and subsequently stored by the application, then rendered in web pages without adequate sanitization or encoding. This allows an attacker to inject malicious scripts that execute in the context of other users' browsers when they view the affected pages. The vulnerability is exploitable remotely over the network (AV:N) with low attack complexity (AC:L), but requires some level of privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. The impact includes limited confidentiality, integrity, and availability losses (C:L/I:L/A:L), as the injected script could steal session tokens, manipulate displayed content, or perform actions on behalf of the user. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published recently in September 2025, suggesting it is a new discovery. Stored XSS in ticketing or event management systems like My Tickets can be particularly dangerous because these platforms often handle user credentials, personal data, and transactional information. Attackers could leverage this vulnerability to conduct phishing, session hijacking, or spread malware within an organization or to its customers. The requirement for some privileges and user interaction implies that attackers might need to have an account or trick users into clicking malicious links, but once exploited, the impact can be significant due to the persistent nature of stored XSS.

For European organizations using Joe Dolson My Tickets, this vulnerability poses a risk to both internal users and customers. Ticketing systems often integrate with payment gateways and store personal data, so exploitation could lead to unauthorized access to sensitive information, fraudulent transactions, or reputational damage. The medium severity rating reflects moderate risk, but the scope change and stored nature of the XSS increase potential damage. Organizations in sectors such as event management, cultural institutions, and transportation that rely on My Tickets could face targeted attacks aiming to steal credentials or disrupt services. Additionally, GDPR compliance requires protection of personal data, so exploitation leading to data breaches could result in regulatory penalties. The lack of known exploits currently provides a window for mitigation, but the public disclosure means attackers may develop exploits soon. The requirement for user interaction and privileges somewhat limits mass exploitation but does not eliminate risk, especially in environments with many users or weak access controls.

1. Immediate mitigation should include implementing strict input validation and output encoding on all user-supplied data rendered in web pages, particularly in ticket descriptions, comments, or user profile fields. 2. Employ Content Security Policy (CSP) headers to restrict script execution sources and reduce the impact of injected scripts. 3. Enforce the principle of least privilege to limit user permissions, reducing the ability of attackers to exploit the vulnerability. 4. Conduct thorough code reviews and security testing focusing on input handling in the My Tickets application. 5. Monitor logs and user activity for unusual behavior indicative of XSS exploitation attempts. 6. Educate users about phishing and suspicious links to reduce the risk of user interaction exploitation. 7. Since no official patch is currently available, consider temporary workarounds such as disabling or restricting features that accept user input until a fix is released. 8. Plan for prompt deployment of official patches once available and verify their effectiveness through penetration testing.
