When parsing multipart HTTP messages, an integer type mismatch between the caller and soup_headers_parse() can cause the length parameter to be incorrectly truncated, leading to a heap buffer over-read. A remote attacker could use this flaw to crash an application using libsoup or potentially disclose heap memory contents.","published_at":"2026-07-21T18:40:52.174000Z","last_modified_at":"2026-08-24T16:45:12.990000Z","cvss_v3_score":4.2,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:L","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-125"],"nvd_references":["https://access.redhat.com/security/cve/CVE-2026-12548","https://bugzilla.redhat.com/show_bug.cgi?id=2489996","https://gitlab.gnome.org/GNOME/libsoup/-/work_items/512"],"vuln_status":"Analyzed","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-07-21T22:30:37.370341Z","updated_at":"2026-08-24T19:35:50.286612Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"H","value_label":"High"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"L","value_label":"Low"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"gnome","vendor_name":"GNOME","product_slug":"libsoup","product_name":"libsoup","version_start":null,"version_start_inclusive":null,"version_end":null,"version_end_inclusive":null,"cpe23_uri":"cpe:2.3:a:gnome:libsoup:-:*:*:*:*:*:*:*"},{"vendor_slug":"redhat","vendor_name":"RedHat","product_slug":"enterprise-linux","product_name":"enterprise_linux","version_start":"10.0","version_start_inclusive":true,"version_end":"10.0","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:o:redhat:enterprise_linux:10.0:*:*:*:*:*:*:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-12548","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2489996","source_type":"MISC","tags":[]},{"url":"https://gitlab.gnome.org/GNOME/libsoup/-/work_items/512","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-07-21T18:40:52.174000Z","label":"CVE published","source":null}]}
