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-2026-116787/ (Markdown: https://insights.sbomify.com/CVE-2026-116787/index.md)","id":"CVE-2026-116787","markdown":"https://insights.sbomify.com/CVE-2026-116787/index.md","name":"CVE-2026-116787","record":{"aliases":["GHSA-j27c-m99r-8pc3"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[{"name":"Freeswitch","product":"freeswitch","vendor":"freeswitch"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-789","name":"Memory Allocation with Excessive Size Value"},{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"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, mod_event_socket used an unauthenticated Content-Length value directly as the allocation size for an Event Socket message body. Negative or extremely large values could overflow the terminator calculation or force an allocation failure through a helper that aborts the FreeSWITCH process. The header is parsed before the Event Socket password, so any host admitted by apply-inbound-acl can trigger termination with its first packet; the default loopback ACL limits ordinary installations to local clients. The outbound socket dialplan path is also affected when FreeSWITCH connects to a hostile application server, and process termination drops every active call until the service is restarted. 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: Pre-authentication process termination in the Event Socket via an unbounded Content-Length","id":"CVE-2026-116787","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: Pre-authentication heap buffer overflow in core XML empty-entity decoding","id":"CVE-2026-116788"},"nickname":null,"packages":[],"prev":{"headline":"FreeSWITCH: Channel-variable injection via SIP REFER leads to command execution in mod_sofia","id":"CVE-2026-116786"},"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":"2026-11-05","vendors":["signalwire"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-116787/"}
