It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-7889 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-7889/ (Markdown: https://insights.sbomify.com/CVE-2018-7889/index.md)","id":"CVE-2018-7889","markdown":"https://insights.sbomify.com/CVE-2018-7889/index.md","name":"CVE-2018-7889","record":{"aliases":["DEBIAN-CVE-2018-7889","GHSA-7hmv-6p8v-7rmw","MGASA-2018-0399","UBUNTU-CVE-2018-7889"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Calibre ebook manager","requires_auth":"none","summary":"Remote attackers can execute arbitrary code by tricking users into opening a crafted bookmark file in Calibre.","user_interaction":"required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"calibre","vendor":"calibre-ebook"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"gui2/viewer/bookmarkmanager.py in Calibre 3.18 calls cPickle.load on imported bookmark data, which allows remote attackers to execute arbitrary code via a crafted .pickle file, as demonstrated by Python code that contains an os.system call.","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":"Deserialization in n/a","id":"CVE-2018-7889","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Command injection in n/a","id":"CVE-2018-7890"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2018-7886"},"products":["n/a"],"published":"2018-03-08","related":[{"cvss_score":9.8,"headline":"Command injection in Calibre","id":"CVE-2011-4124","kev_date_added":null,"published":"2021-10-27"},{"cvss_score":9.8,"headline":"Privilege escalation in Calibre","id":"CVE-2011-4125","kev_date_added":null,"published":"2021-10-27"},{"cvss_score":9.3,"headline":"calibre: Path Traversal Vulnerability Enables Arbitrary File Write and Remote Code Execution","id":"CVE-2026-26064","kev_date_added":null,"published":"2026-02-20"},{"cvss_score":9.3,"headline":"calibre: Path Traversal can Lead to Arbitrary File Write and Potential Code Execution","id":"CVE-2026-26065","kev_date_added":null,"published":"2026-02-20"},{"cvss_score":8.6,"headline":"calibre has a Path Traversal Leading to Arbitrary File Write and Potential Code Execution","id":"CVE-2026-25635","kev_date_added":null,"published":"2026-02-06"},{"cvss_score":8.2,"headline":"calibre has a path traversal vulnerability","id":"CVE-2026-33206","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":8.2,"headline":"calibre has a Path Traversal Leading to Arbitrary File Corruption and Code Execution","id":"CVE-2026-25636","kev_date_added":null,"published":"2026-02-06"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code by tricking users into opening a crafted bookmark file in Calibre.","url":"https://insights.sbomify.com/CVE-2018-7889/"}
