CVE-2026-21812 — Multiple security vulnerabilities affect HCL AppScan Azure Boards Plugin (CVE-2026-12143 and CVE-2026-13149)

HCL AppScan Azure Boards Plugin is affected by a Cleartext Transmission of Sensitive Information vulnerability when configured to communicate with the AppScan server over HTTP. This could allow an attacker to intercept credentials or authentication tokens during transmission. The plugin has been updated to display a warning when HTTP is used and recommend HTTPS for secure communication.

Low

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 0.1% (30-day exploitation probability)+1

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.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

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.

Identify exposed assets running the affected vendor/product/version combinations (HCL Software AppScan Integration with Azure Boards for ASoC & A360).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes matching the vulnerability class (cryptography), errors and authentication anomalies.
