Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-26618 in the wild and no public exploit code.\n\nAffected product: erlang otp. 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-2025-26618/ (Markdown: https://insights.sbomify.com/CVE-2025-26618/index.md)","id":"CVE-2025-26618","markdown":"https://insights.sbomify.com/CVE-2025-26618/index.md","name":"CVE-2025-26618","record":{"aliases":["AZL-57083","AZL-57095","DEBIAN-CVE-2025-26618","GHSA-78cv-45vx-q6fr","MGASA-2025-0088","OESA-2025-1220","SUSE-SU-2025:0901-1","SUSE-SU-2025:1051-1","UBUNTU-CVE-2025-26618","USN-7313-1","openSUSE-SU-2025:14879-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Erlang OTP","requires_auth":"low_privilege","summary":"Authenticated users can cause excessive memory allocation in Erlang OTP SFTP server by sending crafted SSH packets, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","version":"4.0"},"cwes":[{"id":"CWE-789","name":"Memory Allocation with Excessive Size Value"}],"description":"Erlang is a programming language and runtime system for building massively scalable soft real-time systems with requirements on high availability. OTP is a set of Erlang libraries, which consists of the Erlang runtime system, a number of ready-to-use components mainly written in Erlang. Packet size is not verified properly for SFTP packets. As a result when multiple SSH packets (conforming to max SSH packet size) are received by ssh, they might be combined into an SFTP packet which will exceed the max allowed packet size and potentially cause large amount of memory to be allocated. Note that situation described above can only happen for successfully authenticated users after completing the SSH handshake. This issue has been patched in OTP versions 27.2.4, 26.2.5.9, and 25.3.2.18. There are no known workarounds for this vulnerability.","ecosystems":["SUSE:Linux Enterprise Module for Server Applications 15 SP6","openSUSE:Leap 15.6","openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"SSH SFTP packet size not verified properly in Erlang OTP","id":"CVE-2025-26618","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":5,"n_references":2,"next":{"headline":"Vega Cross-Site Scripting (XSS) via event filter when not using CSP mode `expressionInterpeter`","id":"CVE-2025-26619"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Module for Server Applications 15 SP6","fixed":["23.3.4.19-150300.3.17.1"],"introduced":["0"],"last_affected":[],"package":"erlang","purl":"pkg:rpm/suse/erlang\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Server%20Applications%2015%20SP6","source":"SUSE-SU-2025:0901-1"},{"ecosystem":"SUSE:Linux Enterprise Module for Server Applications 15 SP6","fixed":["26.2.1-150300.7.8.1"],"introduced":["0"],"last_affected":[],"package":"erlang26","purl":"pkg:rpm/suse/erlang26\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Server%20Applications%2015%20SP6","source":"SUSE-SU-2025:1051-1"},{"ecosystem":"openSUSE:Leap 15.6","fixed":["23.3.4.19-150300.3.17.1"],"introduced":["0"],"last_affected":[],"package":"erlang","purl":"pkg:rpm/opensuse/erlang\u0026distro=openSUSE%20Leap%2015.6","source":"SUSE-SU-2025:0901-1"},{"ecosystem":"openSUSE:Leap 15.6","fixed":["26.2.1-150300.7.8.1"],"introduced":["0"],"last_affected":[],"package":"erlang26","purl":"pkg:rpm/opensuse/erlang26\u0026distro=openSUSE%20Leap%2015.6","source":"SUSE-SU-2025:1051-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["27.2.4-2.1"],"introduced":["0"],"last_affected":[],"package":"erlang","purl":"pkg:rpm/opensuse/erlang\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2025:14879-1"}],"prev":{"headline":"SQL Injection endpoint 'historico_paciente.php' parameter 'id_fichamedica' in WeGIA","id":"CVE-2025-26617"},"products":["otp"],"published":"2025-02-20","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-03","vendors":["erlang"]},"summary":"Authenticated users can cause excessive memory allocation in Erlang OTP SFTP server by sending crafted SSH packets, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2025-26618/"}
