PYSEC-2026-4130
Vulnerability from pysec - Published: 2026-10-01 16:38 - Updated: 2026-10-01 17:10Impact
OpenCVE contains a Server-Side Request Forgery (SSRF) vulnerability in the notification testing functionality for both Webhook and Slack integrations.
An authenticated user with permission to configure notification channels can trigger test requests to arbitrary HTTP(S) endpoints. Insufficient validation of target destinations allows requests to be sent to hosts reachable from the OpenCVE server, including internal network resources, localhost interfaces, and cloud metadata services.
Successful exploitation could allow an attacker to interact with internal services that are not otherwise accessible from the Internet and retrieve information from HTTP-based services reachable by the OpenCVE instance.
Patches
The vulnerability has been fixed in OpenCVE version 3.0.0, users should upgrade to version 3.0.0 or later.
The fix introduces additional validation of user-supplied URLs used by the notification testing functionality and prevents requests to localhost, private network ranges, link-local addresses, cloud metadata services, and other non-public destinations.
Workarounds
Users unable to upgrade should restrict outbound network access from OpenCVE to trusted external destinations using firewall rules, network policies, or egress filtering.
Where possible, access to localhost interfaces, private network ranges, and cloud metadata services should be blocked from the OpenCVE application environment.
Disabling access to the notification testing functionality also mitigates the issue.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
