No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-116783/ (Markdown: https://insights.sbomify.com/CVE-2026-116783/index.md)","id":"CVE-2026-116783","markdown":"https://insights.sbomify.com/CVE-2026-116783/index.md","name":"CVE-2026-116783","record":{"aliases":["GHSA-mjp3-3cq2-hxj4"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[{"name":"Freeswitch","product":"freeswitch","vendor":"freeswitch"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"FreeSWITCH is a Software Defined Telecom Stack enabling the digital transformation from proprietary telecom switches to a software implementation that runs on any commodity hardware. Prior to 1.11.2, udptl_rx_packet() used a peer-controlled FEC entry count directly to fill five-entry FEC arrays in a mod_spandsp T.38 session. A larger count wrote sender-controlled error-recovery data beyond those arrays and persisted the oversized count for a later reconstruction pass. Any peer able to deliver UDPTL to an established T.38 fax session can reach the parser, including deployments using fax applications or a T.38 gateway. The memory corruption can crash FreeSWITCH and end every active call, although remote code execution has not been demonstrated. This issue is fixed in version 1.11.2.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"FreeSWITCH mod_spandsp: out-of-bounds write parsing UDPTL error-recovery data","id":"CVE-2026-116783","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"FreeSWITCH: Out-of-bounds read in RTCP NACK feedback parsing","id":"CVE-2026-116784"},"nickname":null,"packages":[],"prev":{"headline":"FreeSWITCH: Pre-authentication invalid pointer dereference in mod_rtmp connect command handling","id":"CVE-2026-116782"},"products":["freeswitch"],"published":"2026-11-05","related":[{"cvss_score":9.8,"headline":"SignalWire FreeSwitch Code Injection","id":"CVE-2026-116779","kev_date_added":"2026-11-09","published":"2026-11-05"},{"cvss_score":9.8,"headline":"FreeSWITCH: Pre-authentication heap buffer overflow in `mod_verto` HTTP POST body read","id":"CVE-2026-49841","kev_date_added":null,"published":"2026-06-09"},{"cvss_score":9.8,"headline":"FreeSWITCH 1.6.10 through 1.10.1 has a default password in event_socket.conf.xml.","id":"CVE-2019-19492","kev_date_added":null,"published":"2019-12-02"},{"cvss_score":9.1,"headline":"FreeSWITCH: Pre-authentication heap out-of-bounds write in mod_xml_rpc WebSocket frame length handling","id":"CVE-2026-116785","kev_date_added":null,"published":"2026-11-05"},{"cvss_score":9.1,"headline":"FreeSWITCH: Inbound ICE connectivity checks are accepted without verifying STUN MESSAGE-INTEGRITY","id":"CVE-2026-116790","kev_date_added":null,"published":"2026-11-05"},{"cvss_score":9.1,"headline":"FreeSWITCH: Pre-authentication heap buffer overflow in libesl `Content-Length` parsing","id":"CVE-2026-49840","kev_date_added":null,"published":"2026-06-09"},{"cvss_score":8.8,"headline":"FreeSWITCH: Channel-variable injection via SIP REFER leads to command execution in mod_sofia","id":"CVE-2026-116786","kev_date_added":null,"published":"2026-11-05"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-11-09","vendors":["signalwire"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-116783/"}
