• CVE-2026-46380: 0.14% estimated exploitation activity in the next 30 days; percentile 3.57 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

A source code audit led to the discovery of three significant security vulnerabilities in the trestle/core/remote/cache.py module. Finding 1 (Critical): SSRF (CWE-918) The HTTPSFetcher.dofetch() method passes a user-supplied URL directly to requests.get() without validation. This allows an attacker to perform Server-Side Request Forgery, targeting internal services or cloud metadata endpoints (e.g., 169.254.169.254). Per rule 4.2.11 of the CVE CNA rules Finding 1 will be addressed in this advisory, while findings 2 & 3 will be addressed in separate advisories: --- Multiple Path Traversal Vulnerabilities in Remote Fetching Subsystem Finding 2 & 3 (High/Medium): Path Traversal (CWE-22) The caching logic for HTTPSFetcher and LocalFetcher fails to sanitize URI paths, allowing for arbitrary file reads via file:// or writing cached files outside the intended directory. Impact: These vulnerabilities can be chained to exfiltrate sensitive cloud credentials or compromise CI/CD environments.…

# Patch Next advisory brief: CVE-2026-46380

Advisory: compliance-trestle Vulnerable to SSRF in Remote Fetching Subsystem
IDs: CVE-2026-46380, GHSA-w76h-q7c6-jpjp
Record: https://patchnext.com/advisories/cve-2026-46380 (revision 2, source checked 26 Oct 2026, 13:50 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: compliance-trestle 4.0.3, 3.12.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI compliance-trestle: affected >= 4.0.0, < 4.0.3; < 3.12.2; fixed in 3.12.2, 4.0.3

## Suggested inspection (read-only)
- `python -m pip show compliance-trestle`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on compliance-trestle.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
