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-2021-3538 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/satori/go.uuid (Go): affected from 1.2.1-0.20180103161547-0ef6afb2f6cd; fixed in 1.2.1-0.20180404165556-75cca531ea76\n- github.com/satori/go.uuid (Go): affected from 1.2.1-0.20180103161547-0ef6afb2f6cd; fixed in 1.2.1-0.20180404165556-75cca531ea76\n- github.com/satori/go.uuid (Go): affected from 1.2.1-0.20180103161547-0ef6afb2f6cd; fixed in 1.2.1-0.20180404165556-75cca531ea76\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-2021-3538/ (Markdown: https://insights.sbomify.com/CVE-2021-3538/index.md)","id":"CVE-2021-3538","markdown":"https://insights.sbomify.com/CVE-2021-3538/index.md","name":"CVE-2021-3538","record":{"aliases":["CLEANSTART-2026-NO94084","GHSA-33m6-q9v5-62r7","GO-2022-0244"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Go UUID library","requires_auth":"none","summary":"Predictable UUID generation in the satori/go.uuid library allows attackers to guess identifiers, potentially bypassing security controls or accessing sensitive data.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"uuid","vendor":"satori"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-338","name":"Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)"}],"description":"A flaw was found in github.com/satori/go.uuid in versions from commit 0ef6afb2f6cdd6cdaeee3885a95099c63f18fc8c to d91630c8510268e75203009fe7daf2b8e1d60c45.
