CVE-2026-90455: CWE-1395 Dependency on vulnerable third-party component in CISA Malcolm
A prior update that raised a bundled HTTP client library to a version remediating known vulnerabilities was later reverted, reintroducing the earlier, vulnerable version into a log-processing component. The only code path in that component using the library issues a request to a single fixed, trusted vendor URL at initialization and does not process attacker-controlled input through the library, limiting practical exploitability of the reintroduced version in this context.
AI Analysis
Technical Summary
This vulnerability arises from a regression where a prior update that upgraded a bundled HTTP client library to a secure version was reverted, reintroducing an earlier vulnerable version. The vulnerable library is used solely in a log-processing component to send a request to a single fixed, trusted vendor URL at initialization. No attacker-controlled input is processed through this library in this context, which limits the practical exploitability of the vulnerability.
Potential Impact
The impact is limited due to the constrained use of the vulnerable library. Since the only code path using the vulnerable HTTP client library issues requests to a fixed, trusted vendor URL and does not handle attacker-controlled input, the risk of exploitation is minimal. There are no known exploits in the wild.
Mitigation Recommendations
No official patch or remediation is currently documented. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Given the limited exploitability, immediate urgent action may not be required, but monitoring vendor updates for a fix is recommended.
