CVE-2025-13490 — IBM App Connect Enterprise Certified Container IntegrationServer and IntegrationRuntime operands that report metrics are vulnerable to loss of confidentiality

IBM App Connect Operator versions CD 11.3.0 through 11.6.0 and 12.1.0 through 12.20.0, LTS versions 12.0.0 through 12.0.20, and IBM App Connect Enterprise Certified Containers Operands versions CD 12.0.11.2‑r1 through 12.0.12.5‑r1 and 13.0.1.0‑r1 through 13.0.6.1‑r1, and LTS versions 12.0.12‑r1 through 12.0.12‑r20, contain a vulnerability in which the IBM App Connect Enterprise Certified Container transmits data in clear text, potentially allowing an attacker to intercept and obtain sensitive information through man‑in‑the‑middle techniques.

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 0.2% (30-day exploitation probability)+1
Technical severity (medium)+3

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 (Ibm App Connect Enterprise Certified Containers Operands, Ibm App Connect Operator).
The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
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.

What should defenders know first?

CVE-2025-13490 is "IBM App Connect Enterprise Certified Container IntegrationServer and IntegrationRuntime operands that report metrics are vulnerable to loss of confidentiality", rated Medium. It affects App Connect Enterprise Certified Containers Operands (Ibm); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 5.9 describes technical severity. EPSS 0.19% 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.
