Title
Trawl 1.5.0 before 1.10.0 SSRF via IPv4-mapped IPv6 MCP Policy Bypass
Summary
Trawl 1.5.0 before 1.10.0 contains a server-side request forgery vulnerability that allows unauthenticated attackers to bypass the MCP outbound URL policy using IPv4-mapped IPv6 addresses. Attackers can supply hex-normalized addresses like ::ffff:7f00:1 directly or via redirects to fetch loopback, private, and cloud metadata services and read responses.
Severity
5.8 (Medium)
CWE
- CWE-918 - Server-Side Request Forgery (SSRF)

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
