A vulnerability in usememos through version 0.30.0 allows a remote authenticated attacker to perform Server-Side Request Forgery (SSRF) via the webhook validation mechanism. The issue arises from the ability to set a webhook target to an internal address, potentially enabling unauthorized internal network requests.
AI Analysis
Technical Summary
The usememos application versions up to and including 0.30.0 contain a vulnerability in the webhook validation logic located in internal/webhook/validate.go. This flaw permits a remote attacker with authentication to specify webhook targets that point to internal network addresses, enabling Server-Side Request Forgery (SSRF) attacks. No CVSS score or detailed impact metrics are provided. No patch or remediation information is available from the source data.
Potential Impact
An authenticated attacker can exploit this vulnerability to make the server send requests to internal network resources that may not be otherwise accessible. This could lead to unauthorized access or information disclosure within the internal network. The exact impact depends on the internal network configuration and what services are reachable via SSRF.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict or monitor authenticated users' ability to configure webhook targets to prevent pointing to internal addresses.
