An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-1788 in the wild and no public exploit code.\n\nAffected product: Xquic Server. 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-2026-1788/ (Markdown: https://insights.sbomify.com/CVE-2026-1788/index.md)","id":"CVE-2026-1788","markdown":"https://insights.sbomify.com/CVE-2026-1788/index.md","name":"CVE-2026-1788","record":{"aliases":["GHSA-xccv-2cc3-7px5","ROOT-OS-UBUNTU-2204-CVE-2026-1788"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"QUIC server library","requires_auth":"none","summary":"An out-of-bounds write in the Xquic Server packet processing module allows attackers to execute arbitrary code or cause denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"alibaba","cpe":[],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/AU:Y/R:U/RE:M/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":": Out-of-bounds Write vulnerability in Xquic Project Xquic Server xquic on Linux (QUIC protocol implementation, packet processing module modules) allows : Buffer Manipulation.This issue affects Xquic Server: through 1.8.3.","ecosystems":[],"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":"Buffer Overflow in Xquic Server","id":"CVE-2026-1788","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in MF842CDW","id":"CVE-2026-1789"},"packages":[],"prev":{"headline":"LearnPress Export Import \u003c= 4.1.0 - Missing Authentication to Unauthenticated Migrated Course Deletion","id":"CVE-2026-1787"},"products":["Xquic Server"],"published":"2026-02-03","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-02-03","vendors":["Xquic Project"]},"summary":"An out-of-bounds write in the Xquic Server packet processing module allows attackers to execute arbitrary code or cause denial of service.","url":"https://insights.sbomify.com/CVE-2026-1788/"}
