An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-21126 exists.\n\nAffected packages and fixed versions:\n- com.github.samtools:htsjdk (Maven): affected all versions; fixed in 3.0.1\n- com.github.samtools:htsjdk (Maven): affected all versions; fixed in 3.0.1\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-2022-21126/ (Markdown: https://insights.sbomify.com/CVE-2022-21126/index.md)","id":"CVE-2022-21126","markdown":"https://insights.sbomify.com/CVE-2022-21126/index.md","name":"CVE-2022-21126","record":{"aliases":["GHSA-96vh-4rfp-c42c","UBUNTU-CVE-2022-21126"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Java bioinformatics library","requires_auth":"none","summary":"Attackers can exploit insecure temporary file creation to read or modify data, affecting users of the htsjdk Java library.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"htsjdk","vendor":"samtools"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-668","name":"Exposure of Resource to Wrong Sphere"}],"description":"The package com.github.samtools:htsjdk before 3.0.1 are vulnerable to Creation of Temporary File in Directory with Insecure Permissions due to the createTempDir() function in util/IOUtil.java not checking for the existence of the temporary directory before attempting to create it.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Creation of Temporary File in Directory with Insecure Permissions","id":"CVE-2022-21126","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"other","year":"2022"},"n_packages":2,"n_references":3,"next":{"headline":"Information disclosure in Intel(R) Processors","id":"CVE-2022-21127"},"packages":[{"ecosystem":"Maven","fixed":["3.0.1"],"introduced":["0"],"last_affected":[],"package":"com.github.samtools:htsjdk","purl":null,"source":"GHSA-96vh-4rfp-c42c"},{"ecosystem":"Maven","fixed":["3.0.1"],"introduced":["0"],"last_affected":[],"package":"com.github.samtools:htsjdk","purl":"pkg:maven/com.github.samtools/htsjdk","source":"GHSA-96vh-4rfp-c42c"}],"prev":{"headline":"Information disclosure in Intel(R) Processors","id":"CVE-2022-21125"},"products":["com.github.samtools:htsjdk"],"published":"2022-11-29","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-24","vendors":["n/a"]},"summary":"Attackers can exploit insecure temporary file creation to read or modify data, affecting users of the htsjdk Java library.","url":"https://insights.sbomify.com/CVE-2022-21126/"}
