Summary
libsoup2.4, libsoup3 vulnerabilities
Details
It was discovered that libsoup incorrectly handled certain URLs when using an HTTP proxy. A remote attacker could possibly use this issue to inject arbitrary HTTP headers. (CVE-2026-1467)
It was discovered that libsoup did not remove proxy authentication credentials when following HTTP redirects. A remote attacker could possibly use this issue to obtain sensitive information. (CVE-2026-1539)
Ahmed Lekssays discovered that libsoup incorrectly parsed certain HTTP requests. A remote attacker could possibly use this issue to obtain sensitive information. (CVE-2026-1801)

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.
