CVE-2025-12626 is a path traversal vulnerability identified in the jeecgboot jeewx-boot software, affecting versions up to commit 641ab52c3e1845fec39996d7794c33fb40dad1dd. The flaw resides in the getImgUrl function within the WxActGoldeneggsPrizesController.java file, where the imgurl parameter is insufficiently sanitized. Attackers can manipulate this parameter to traverse directories and access files outside the intended directory scope. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing its risk profile. Although an initial patch was implemented, it was incomplete, as attackers can evade it using additional encoding techniques to bypass filters. The product’s rolling release model means no fixed version numbers are provided for affected or patched releases, complicating vulnerability management. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges or user interaction needed, and low impact on confidentiality, integrity, and availability, resulting in a medium severity score of 5.3. While no active exploitation has been reported, the public release of exploit code raises the likelihood of future attacks. The vulnerability could allow unauthorized reading of sensitive files, potentially exposing configuration files, credentials, or other critical data, posing a confidentiality risk. The lack of integrity or availability impact suggests the exploit is primarily for information disclosure rather than system disruption.

For European organizations, this vulnerability poses a risk of unauthorized disclosure of sensitive internal files, which could include configuration files, credentials, or proprietary data. Such exposure could facilitate further attacks, including privilege escalation or lateral movement within networks. Organizations relying on jeecgboot jeewx-boot in web applications, especially those handling sensitive or regulated data, may face compliance risks under GDPR if personal data is exposed. The remote and unauthenticated nature of the exploit increases the attack surface, particularly for internet-facing services. Although the impact on system integrity and availability is low, the confidentiality breach potential can lead to reputational damage, financial loss, and regulatory penalties. The rolling release model complicates patch management, potentially delaying remediation and increasing exposure time. European sectors with critical infrastructure or high-value data processed via affected systems are particularly vulnerable to targeted exploitation attempts.

To mitigate CVE-2025-12626, organizations should implement strict input validation and sanitization for the imgurl parameter, ensuring that directory traversal sequences (e.g., ../) and encoded variants are effectively blocked. Employ canonicalization techniques to normalize inputs before validation to prevent bypass via encoding. Use allowlists restricting file access to specific directories or file types. Monitor web application logs for suspicious requests containing traversal patterns or unusual encoding. Deploy web application firewalls (WAFs) with rules targeting path traversal attempts, including encoded payloads. Since the product uses a rolling release model, maintain close communication with the jeecgboot project for timely updates and patches. Conduct regular code reviews focusing on input handling in affected components. If possible, isolate or sandbox the affected functionality to limit file system access. Finally, educate developers on secure coding practices related to file path handling and encoding issues.
