CVE-2026-2849 is a vulnerability identified in the yeqifu warehouse software, specifically within the Cache Sync Handler component's cache management functions: deleteCache, removeAllCache, and syncCache. These functions reside in the CacheController.java file and suffer from improper access control implementation, allowing unauthorized remote attackers to invoke cache manipulation operations. The vulnerability is exploitable remotely without user interaction and requires low privileges, indicating that an attacker with limited access could escalate their capabilities by manipulating cache data. The improper access control could lead to unauthorized deletion, modification, or synchronization of cached data, potentially disrupting application behavior or exposing sensitive information. The product follows a rolling release model, which means continuous updates without fixed version numbers, complicating patch identification and deployment. Although the vulnerability has been publicly disclosed, the vendor has not yet responded or provided a patch, increasing the risk of exploitation. The CVSS 4.0 score of 5.3 reflects a medium severity, considering the ease of exploitation and the impact on confidentiality, integrity, and availability. No known exploits are currently reported in the wild, but public disclosure raises the likelihood of future exploitation attempts.

The vulnerability can have significant impacts on organizations using yeqifu warehouse software. Unauthorized cache manipulation can lead to data integrity issues, where attackers may delete or alter cached data, causing application errors or incorrect data being served. This can disrupt business operations, especially if the cache is critical for performance or data consistency. Confidentiality may be compromised if cache data includes sensitive information accessible through these functions. Availability can also be affected if cache removal or synchronization is abused to degrade system performance or cause denial of service. Since the exploit requires only low privileges and no user interaction, attackers who gain minimal access could leverage this vulnerability to escalate their control or disrupt services. The lack of vendor response and patch increases exposure time, raising the risk for organizations globally. Industries relying on supply chain or warehouse management systems are particularly vulnerable to operational disruptions and potential data breaches.

Organizations should immediately audit and restrict access controls around the Cache Sync Handler functions in yeqifu warehouse, ensuring that only authorized and authenticated users with appropriate privileges can invoke cache operations. Implement network-level segmentation and firewall rules to limit remote access to the affected components. Monitor logs for unusual cache operation activity, such as unexpected deletions or synchronizations, to detect potential exploitation attempts early. If possible, deploy application-layer access controls or web application firewalls (WAFs) to block unauthorized requests targeting these cache functions. Engage with the yeqifu project maintainers or community to track any forthcoming patches or updates. Consider temporary workarounds such as disabling remote cache management features if feasible until a patch is available. Regularly back up cache-related data and configurations to enable recovery from malicious modifications. Finally, educate system administrators and developers about the risks of improper access controls and enforce secure coding practices to prevent similar vulnerabilities.
