CVE-2025-53329 is a high-severity vulnerability affecting the szajenw Społecznościowa 6 PL 2013 software, specifically versions up to 2.0.6. The vulnerability is classified as a Cross-Site Request Forgery (CSRF) issue (CWE-352) that enables an attacker to perform unauthorized actions on behalf of an authenticated user. In this case, the CSRF vulnerability allows for Stored Cross-Site Scripting (XSS) attacks, which means that malicious scripts can be injected and permanently stored within the application, potentially affecting all users who access the compromised content. The CVSS 3.1 base score is 7.1, indicating a high severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L) shows that the attack can be launched remotely over the network without privileges, requires user interaction, and impacts confidentiality, integrity, and availability with low to moderate impact. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. The lack of available patches at the time of publication increases the risk for organizations using this software. The vulnerability's exploitation could lead to unauthorized actions, data leakage, session hijacking, or further compromise of the affected systems through the stored XSS payloads.

For European organizations using szajenw Społecznościowa 6 PL 2013, this vulnerability poses significant risks. The CSRF combined with stored XSS can lead to unauthorized actions performed in the context of legitimate users, potentially resulting in data breaches, defacement, or further malware injection. This can compromise user data confidentiality and integrity, disrupt service availability, and damage organizational reputation. Given that Społecznościowa 6 PL 2013 appears to be a social/community platform (as suggested by the name), organizations relying on it for internal or external communication could face operational disruptions and loss of trust. The cross-site nature of the attack means that users interacting with the platform from any location, including European countries, are at risk. Additionally, the vulnerability’s ability to affect multiple users via stored XSS increases the attack surface and potential impact. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once patches are available or if the vulnerability becomes public knowledge.

Organizations should prioritize upgrading to a patched version of Społecznościowa 6 PL 2013 once available. In the absence of patches, immediate mitigations include implementing strict anti-CSRF tokens in all state-changing requests to prevent unauthorized actions. Web application firewalls (WAFs) can be configured to detect and block suspicious CSRF and XSS payloads. Input validation and output encoding should be enforced rigorously to mitigate stored XSS risks. User education to recognize phishing attempts and suspicious links can reduce the likelihood of user interaction required for exploitation. Additionally, organizations should review and limit user permissions to the minimum necessary to reduce potential damage. Monitoring and logging of unusual user activities can help detect exploitation attempts early. Network segmentation and restricting access to the application to trusted networks or VPN users can further reduce exposure.
