Given the current state of the vulnerability, organizations are advised to monitor for any signs of exploitation. The availability of a proof of concept means that it may be leveraged by attackers in the wild, making swift remediation crucial.
Vulnerability Details
A flaw has been found in devlikeapro WAHA up to 2026.3.4. This affects an unknown function of the file src/api/media.controller.ts of the component API Request Handler. This manipulation causes server-side request forgery.
The CVSS score for this vulnerability is 5.3, classified as medium severity. This score indicates that while the vulnerability poses a risk, the potential for widespread impact is moderate.
The vulnerability was published on April 25, 2026, and is categorized under CWE-918, which indicates a server-side request forgery issue.
Technical Analysis
The root cause of this vulnerability lies in insufficient validation of user input in the API Request Handler, specifically in the media controller. This flaw can be exploited by attackers to manipulate server requests, potentially leading to unauthorized access to internal services.
The attack vector is network-based, allowing remote attackers to exploit this vulnerability without needing physical access to the system. The attack complexity is low, as attackers can initiate the exploitation without special conditions. Only low privileges are required to successfully execute an attack.
User interaction is not required for the exploitation of this vulnerability, making it particularly concerning for organizations. The impact on confidentiality, integrity, and availability is classified as low, but the potential for further exploitation through lateral movements within the network could lead to more significant breaches.
Risk & Impact Analysis
The real-world risk posed by this vulnerability is significant. Attackers may leverage the server-side request forgery to access internal applications or services, potentially resulting in the exposure of sensitive data or further attacks against internal systems.
Organizations should assess the blast radius of this vulnerability, particularly those utilizing the affected version of WAHA. Due to the nature of server-side request forgery, the potential for lateral movement within the network increases, amplifying the urgency for remediation.
With a CVSS score of 5.3 and the vulnerability not included in the KEV catalog, organizations must actively monitor their systems for signs of exploitation. The EPSS score of 0.000340000 indicates a low probability of exploitation, but organizations should not become complacent.

Affected Versions
All versions of devlikeapro WAHA prior to 2026.3.4 are affected by this vulnerability, particularly those utilizing the API Request Handler component.
Mitigation & Remediation
Organizations should prioritize patching immediately. Updating to the latest version of WAHA will close this vulnerability. If an immediate update is not possible, organizations should implement network controls to restrict access to the affected component.
Configuration hardening should be considered as a temporary measure, ensuring that only necessary functions are exposed to the network. Additionally, continuous monitoring for unusual network activity is recommended.
For further guidance, organizations can refer to resources on penetration testing to validate the effectiveness of their remediation efforts.
Detection Guidance
Organizations should monitor logs for any indications of server-side request forgery attempts. Look for unusual patterns in API calls, particularly those that involve media URLs. Behavioral anomalies in network traffic may also indicate attempts to exploit this vulnerability.
Implementing network signatures to detect exploitation attempts may help in identifying active attacks. Regular reviews of system configurations can also assist in detecting unauthorized changes.
