• CVE-2026-107841: 0.23% estimated exploitation activity in the next 30 days; percentile 14.24 (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.

Impact pacioli-guard's document-layer consent gate requires a human-minted, single-use, document-bound and act-bound marker before a credential carrying API Key Scope.requireconsent may submit or cancel a document. Because ERPNext performs further document writes as a consequence of a governed act, nested acts are allowed to "ride" the consent established by the enclosing act instead of needing a marker of their own. The ride predicate returned true for every cancel, regardless of which act the enclosing marker authorised. Riding never reaches consentverdict, which is where the marker-to-act binding is enforced. The result: any Document.cancel() performed inside an act that had established consent reached docstatus = 2 with no marker, no act-binding check, no single-use spend, and no denial audit row. This is reachable with the exact grant an operator is documented to give the broker, and the cancelled document's identity is caller-controlled: - Sales Invoice.onsubmit…

# Patch Next advisory brief: CVE-2026-107841

Advisory: pacioli: A submit consent marker licensed cancellation of caller-named pre-existing documents
IDs: CVE-2026-107841, GHSA-3hj7-6vmj-h8v4
Record: https://patchnext.com/advisories/cve-2026-107841 (revision 3, source checked 26 Oct 2026, 13:55 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: pacioli-guard 0.10.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI pacioli-guard: affected >= 0.9.6, < 0.10.0; fixed in 0.10.0

## Suggested inspection (read-only)
- `python -m pip show pacioli-guard`: 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 pacioli-guard.
- 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.
