CVE-2026-82208 (GCVE-0-2026-82208)

Vulnerability from cvelistv5 – Published: 2026-09-06 17:49 – Updated: 2026-09-15 06:03

Title

wolfSSL CA-cache hit overrides callback

Summary

With the wolfSSL backend, when CA caching is enabled and an `CURLOPT_SSL_CTX_FUNCTION` callback replaces the trust store, libcurl can silently reinstall the cached store after the callback returns. A certificate trusted by the cached store but rejected by the callback-selected store is then incorrectly accepted.

Severity

7.5 (High)

GHSA-8RQ8-F59M-9CJG

Vulnerability from github – Published: 2026-09-06 18:34 – Updated: 2026-09-08 21:33

Details

With the wolfSSL backend, when CA caching is enabled and an CURLOPT_SSL_CTX_FUNCTION callback replaces the trust store, libcurl can silently reinstall the cached store after the callback returns. A certificate trusted by the cached store but rejected by the callback-selected store is then incorrectly accepted.

Severity

7.5 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
