The soup_uri_decode_data_uri() function incorrectly treated base64 data-URI payloads as NUL-terminated strings when calling g_base64_decode_inplace(). If the percent-decoded payload contained embedded NUL bytes, the decoded length could remain uninitialized and be used as the size of the returned GBytes. This can lead to an out-of-bounds read or application crash when processing a crafted data URI.","published_at":"2026-09-29T17:15:14.482000Z","last_modified_at":"2026-10-15T17:17:09.120000Z","cvss_v3_score":8.2,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","cvss_v3_severity":"HIGH","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/errata/RHSA-2026:83618","https://access.redhat.com/security/cve/CVE-2026-102555","https://bugzilla.redhat.com/show_bug.cgi?id=2543224"],"vuln_status":"Modified","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":"2026-09-29T18:38:54.211902Z","updated_at":"2026-10-20T02:20:54.235708Z"},"effective_severity":"HIGH","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":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"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":"H","value_label":"High"}]},"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":"3.7.3","version_end_inclusive":false,"cpe23_uri":"cpe:2.3:a:gnome:libsoup:*:*:*:*:*:*:*:*"},{"vendor_slug":"redhat","vendor_name":"redhat","product_slug":"enterprise-linux","product_name":"enterprise_linux","version_start":"9.0","version_start_inclusive":true,"version_end":"9.0","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:o:redhat:enterprise_linux:9.0:*:*:*:*:*:*:*"},{"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/errata/RHSA-2026:83618","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://access.redhat.com/security/cve/CVE-2026-102555","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2543224","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-09-29T17:15:14.482000Z","label":"CVE published","source":null}]}
