CVE-2026-101139 — Webkul Bagisto Invoice Mass Status Update state authorization

A vulnerability was detected in Webkul Bagisto up to 2.4.6/2.5.0-beta4. This impacts an unknown function of the file /admin/sales/invoices/mass-update/state of the component Invoice Mass Status Update. Performing a manipulation results in missing authorization. The attack can be initiated remotely. The exploit is now public and may be used. Upgrading to version 2.5.0-beta5 will fix this issue. The patch is named 2c34b94d0313824ce98efee8aef8ee141d9b89d0. It is recommended to apply a patch to fix this issue. The vendor confirms: "[W]e run continuous automated AI-assisted security scanning across the Bagisto codebase. The behaviour you describe has already been identified and reproduced internally, and it is actively being fixed rather than triaged from scratch."

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.3% (30-day exploitation probability)+3
  • CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Webkul Bagisto).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.

What should defenders know first?

CVE-2026-101139 is "Webkul Bagisto Invoice Mass Status Update state authorization", rated Low. It affects Bagisto (Webkul); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 2.7 describes technical severity. EPSS 0.32% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
