The function value_from_inheritable_property() in css-apply.c recurses through the CSS property inheritance chain without a depth limit, exhausting the process stack and causing a crash in any application using MuPDF for EPUB rendering.","published_at":"2026-06-23T17:21:48.562000Z","last_modified_at":null,"cvss_v3_score":6.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cvss_v3_severity":"MEDIUM","cvss_v4_score":7.1,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-674"],"nvd_references":["https://github.com/ArtifexSoftware/mupdf/releases/tag/1.27.0-rc1","https://bugs.ghostscript.com/show_bug.cgi?id=708840","https://github.com/ArtifexSoftware/mupdf/commit/70b71ab22e6de4d4c44cd301c88231f623a4e94e","https://www.vulncheck.com/advisories/mupdf-rc1-stack-exhaustion-dos-via-epub-css-rendering"],"vuln_status":null,"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":"2026-06-28T17:49:45.838521Z","updated_at":"2026-06-28T23:28:30.475082Z"},"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":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"P","value_label":"Passive"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"N","value_label":"None"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"N","value_label":"None"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"H","value_label":"High"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"artifexsoftware","vendor_name":"ArtifexSoftware","product_slug":"mupdf","product_name":"mupdf","version_start":"0","version_start_inclusive":true,"version_end":"1.27.0-rc1","version_end_inclusive":false,"cpe23_uri":"cve5:artifexsoftware:mupdf:0:1.27.0-rc1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/ArtifexSoftware/mupdf/releases/tag/1.27.0-rc1","source_type":"PATCH","tags":["patch"]},{"url":"https://bugs.ghostscript.com/show_bug.cgi?id=708840","source_type":"MISC","tags":[]},{"url":"https://github.com/ArtifexSoftware/mupdf/commit/70b71ab22e6de4d4c44cd301c88231f623a4e94e","source_type":"PATCH","tags":["patch"]},{"url":"https://www.vulncheck.com/advisories/mupdf-rc1-stack-exhaustion-dos-via-epub-css-rendering","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2026-06-23T17:21:48.562000Z","label":"CVE published","source":null}]}
