Prior to 16.0.6 and 17.0.5.4, the FreePBX Text-To-Speech module allows an authenticated administrator to save a TTS destination name that is HTML-encoded for storage, decoded during dialplan generation, passed as an AGI argument, and used to build filenames inside agi-bin/propolys-tts.agi. The TTS destination name reaches a raw shell-command execution path, allowing arbitrary operating-system command execution as the asterisk service user. This issue is fixed in versions 16.0.6 and 17.0.5.4.","published_at":"2026-08-13T21:23:01.070000Z","last_modified_at":"2026-10-24T15:10:00.190000Z","cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":7.5,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":false,"ssvc_technical_impact":"total","cwes":["CWE-78"],"nvd_references":["https://github.com/FreePBX/security-reporting/security/advisories/GHSA-hg3v-m857-mvw9","https://github.com/FreePBX/tts/commit/37cf0dd3e9ceb4a32e09a2fca6a145320245c0a0","https://github.com/FreePBX/tts/commit/4057410439e66d8be2b47c6358de5fab498bbc21"],"vuln_status":"Awaiting Analysis","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":"2026-08-13T23:20:52.866618Z","updated_at":"2026-10-25T12:33:38.660090Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"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":"P","value_label":"Present"},{"metric":"PR","name":"Privileges Required","value":"H","value_label":"High"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"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":"freepbx","vendor_name":"FreePBX","product_slug":"tts","product_name":"tts","version_start":"< 16.0.6","version_start_inclusive":true,"version_end":"< 16.0.6","version_end_inclusive":true,"cpe23_uri":"cve5:freepbx:tts:< 16.0.6:< 16.0.6"},{"vendor_slug":"freepbx","vendor_name":"FreePBX","product_slug":"tts","product_name":"tts","version_start":">= 17.0.1, < 17.0.5.4","version_start_inclusive":true,"version_end":">= 17.0.1, < 17.0.5.4","version_end_inclusive":true,"cpe23_uri":"cve5:freepbx:tts:>= 17.0.1, < 17.0.5.4:>= 17.0.1, < 17.0.5.4"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/FreePBX/security-reporting/security/advisories/GHSA-hg3v-m857-mvw9","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/FreePBX/tts/commit/37cf0dd3e9ceb4a32e09a2fca6a145320245c0a0","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/FreePBX/tts/commit/4057410439e66d8be2b47c6358de5fab498bbc21","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-08-13T21:23:01.070000Z","label":"CVE published","source":null},{"type":"ssvc_changed","at":"2026-08-18T02:40:44.495625Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-08-18T02:40:44.495625Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-08-18T02:40:44.495625Z","label":"SSVC decision revised","source":"vulnrichment"}]}
