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-2026-116788/ (Markdown: https://insights.sbomify.com/CVE-2026-116788/index.md)","id":"CVE-2026-116788","markdown":"https://insights.sbomify.com/CVE-2026-116788/index.md","name":"CVE-2026-116788","record":{"aliases":["GHSA-f73w-xph4-pjp3"],"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-131","name":"Incorrect Calculation of Buffer Size"},{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"FreeSWITCH is an open-source software telecommunications platform. Before version 1.11.2, an integer underflow in  switch_xml_decode()  can cause an undersized heap allocation when an XML document declares an entity with an empty replacement value. Subsequent copying overruns the allocated buffer. An unauthenticated attacker who can reach a SIP profile with presence management enabled and DTD processing permitted can trigger the vulnerability through a crafted SIP PUBLISH request. Exploitation can corrupt heap memory and terminate the FreeSWITCH process, interrupting all active calls. This vulnerability 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 heap buffer overflow in core XML empty-entity decoding","id":"CVE-2026-116788","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: DTLS-SRTP peer certificate is not bound to the SDP fingerprint when FreeSWITCH is the DTLS server","id":"CVE-2026-116789"},"nickname":null,"packages":[],"prev":{"headline":"FreeSWITCH: Pre-authentication process termination in the Event Socket via an unbounded Content-Length","id":"CVE-2026-116787"},"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-2026-116788/"}
