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-2026-83530 in the wild and no public exploit code.\n\nAffected product: Google cel-go. 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-2026-83530/ (Markdown: https://insights.sbomify.com/CVE-2026-83530/index.md)","id":"CVE-2026-83530","markdown":"https://insights.sbomify.com/CVE-2026-83530/index.md","name":"CVE-2026-83530","record":{"aliases":["AZL-100914","AZL-100917","AZL-100932","AZL-100935","AZL-100938","AZL-100944","AZL-100950","BELL-CVE-2026-83530","DEBIAN-CVE-2026-83530","GHSA-c2gw-4533-c2w3","UBUNTU-CVE-2026-83530"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CEL expression library","requires_auth":"none","summary":"An attacker can cause excessive memory allocation by providing oversized expressions, leading to denial of service in applications using cel-go.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[{"product":"common_expression_language","vendor":"google"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-789","name":"Memory Allocation with Excessive Size Value"}],"description":"A user could provide an expression whose string length is longer than the ParserExpressionSizeLimit() configured on the CEL environment, and a memory allocation would occur proportional to the size of the input before the limit would be checked / enforced.","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":"Uncontrolled Memory Allocation in cel-go","id":"CVE-2026-83530","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Camel: Camel-Dynamic-Router Control Endpoint Compiles Predicate Expressions Supplied by Control Messages","id":"CVE-2026-83531"},"packages":[],"prev":{"headline":"Auth bypass in Sentry","id":"CVE-2026-83527"},"products":["cel-go"],"published":"2026-09-09","related":[],"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":"2026-09-09","vendors":["Google"]},"summary":"An attacker can cause excessive memory allocation by providing oversized expressions, leading to denial of service in applications using cel-go.","url":"https://insights.sbomify.com/CVE-2026-83530/"}
