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-2026-54417 in the wild and no public exploit code.\n\nAffected product: rxi microtar. 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-2026-54417/ (Markdown: https://insights.sbomify.com/CVE-2026-54417/index.md)","id":"CVE-2026-54417","markdown":"https://insights.sbomify.com/CVE-2026-54417/index.md","name":"CVE-2026-54417","record":{"aliases":["GHSA-w3fj-cqg8-8572"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"C tar library","requires_auth":"none","summary":"A remote attacker can cause a denial of service via infinite loop in the microtar library by submitting a crafted tar archive exploiting an integer overflow.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TuranSec","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-835","name":"Loop with Unreachable Exit Condition"},{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"An integer overflow in the mtar_next function in src/microtar.c in rxi microtar 0.1.0 allows a remote attacker to cause a denial of service (uncontrolled CPU consumption / infinite loop) via a crafted tar archive. mtar_next computes the offset to the next record as round_up(h.size, 512) + sizeof(mtar_raw_header_t) using 32-bit arithmetic.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Integer Overflow in rxi/microtar mtar_next() Causes Infinite Loop DoS","id":"CVE-2026-54417","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Leantime - Missing Authorization on TwoFA JSON-RPC Methods Allows Cross-Account 2FA Secret Disclosure and Bypass","id":"CVE-2026-54418"},"packages":[],"prev":{"headline":"Pluck CMS - Unrestricted File Upload via Missing .php8 Extension in Upload Blacklist","id":"CVE-2026-54416"},"products":["microtar"],"published":"2026-06-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["rxi"]},"summary":"A remote attacker can cause a denial of service via infinite loop in the microtar library by submitting a crafted tar archive exploiting an integer overflow.","url":"https://insights.sbomify.com/CVE-2026-54417/"}
