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-2026-90778 in the wild and no public exploit code.\n\nAffected product: sipp. 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-2026-90778/ (Markdown: https://insights.sbomify.com/CVE-2026-90778/index.md)","id":"CVE-2026-90778","markdown":"https://insights.sbomify.com/CVE-2026-90778/index.md","name":"CVE-2026-90778","record":{"aliases":["GHSA-w99r-9mmj-g2pr"],"analysis":{"component_type":"developer_tool","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SIPp load testing tool","requires_auth":"none","summary":"Unauthenticated remote attackers can crash the SIPp process by sending crafted SIP messages with oversized To header tags.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","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","version":"4.0"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"SIPp through 3.7.7 contains a buffer overflow vulnerability in get_peer_tag() function when processing SIP To headers with tag parameters of 2049 bytes or more.
