An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-112063 exists.\n\nAffected product: libstrophe. 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-2026-112063/ (Markdown: https://insights.sbomify.com/CVE-2026-112063/index.md)","id":"CVE-2026-112063","markdown":"https://insights.sbomify.com/CVE-2026-112063/index.md","name":"CVE-2026-112063","record":{"aliases":["DEBIAN-CVE-2026-112063","GHSA-37wj-432m-6r6f","UBUNTU-CVE-2026-112063"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"XMPP client library","requires_auth":"none","summary":"A malicious XMPP server can trigger a stack-based buffer overflow in libstrophe by sending an oversized SCRAM salt, potentially causing code execution or crashes.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"libstrophe through 0.14.0 contains a stack-based buffer overflow vulnerability in SCRAM_Hi that allows malicious XMPP servers to overflow a 128-byte stack buffer by sending an oversized SCRAM salt.
