It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-24859 exists.\n\nAffected packages and fixed versions:\n- pypdf2 (PyPI): affected all versions; fixed in 1.27.5\n- pypdf2 (PyPI): affected all versions; fixed in 1.27.5\n- PyPDF2 (PyPI): affected all versions; fixed in 1.27.5\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-2022-24859/ (Markdown: https://insights.sbomify.com/CVE-2022-24859/index.md)","id":"CVE-2022-24859","markdown":"https://insights.sbomify.com/CVE-2022-24859/index.md","name":"CVE-2022-24859","record":{"aliases":["DEBIAN-CVE-2022-24859","DLA-3039-1","DLA-3451-1","GHSA-xcjx-m2pj-8g79","MGASA-2022-0224","PYSEC-2022-194","UBUNTU-CVE-2022-24859","USN-6176-1","openSUSE-SU-2024:0366-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Python PDF library","requires_auth":"none","summary":"An attacker can cause a denial of service via an infinite loop in PyPDF2 by crafting a malicious PDF with manipulated inline images.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"pypdf2","vendor":"pypdf2_project"}],"cvss":{"score":6.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"PyPDF2 is an open source python PDF library capable of splitting, merging, cropping, and transforming the pages of PDF files. In versions prior to 1.27.5 an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop if the PyPDF2 if the code attempts to get the content stream. The reason is that the last while-loop in `ContentStream._readInlineImage` only terminates when it finds the `EI` token, but never actually checks if the stream has already ended. This issue has been resolved in version `1.27.5`. Users unable to upgrade should validate and PDFs prior to iterating over their content stream.","ecosystems":["PyPI","SUSE:Package Hub 15 SP6","openSUSE:Leap 15.6"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Manipulated inline images can cause Infinite Loop in PyPDF2","id":"CVE-2022-24859","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"debian:debian_linux","products":["debian:debian_linux"],"type":"denial_of_service","year":"2022"},"n_packages":5,"n_references":6,"next":{"headline":"Databasir 1.01 has Use of Hard-coded Cryptographic Key vulnerability.","id":"CVE-2022-24860"},"packages":[{"ecosystem":"PyPI","fixed":["1.27.5"],"introduced":["0"],"last_affected":[],"package":"PyPDF2","purl":null,"source":"GHSA-xcjx-m2pj-8g79"},{"ecosystem":"PyPI","fixed":["1.27.5"],"introduced":["0"],"last_affected":[],"package":"pypdf2","purl":"pkg:pypi/pypdf2","source":"GHSA-xcjx-m2pj-8g79"},{"ecosystem":"PyPI","fixed":["1.27.5"],"introduced":["0"],"last_affected":[],"package":"pypdf2","purl":"pkg:pypi/pypdf2","source":"PYSEC-2022-194"},{"ecosystem":"SUSE:Package Hub 15 SP6","fixed":["1.26.0-bp156.4.3.1"],"introduced":["0"],"last_affected":[],"package":"python-PyPDF2","purl":"pkg:rpm/suse/python-PyPDF2\u0026distro=SUSE%20Package%20Hub%2015%20SP6","source":"openSUSE-SU-2024:0366-1"},{"ecosystem":"openSUSE:Leap 15.6","fixed":["1.26.0-bp156.4.3.1"],"introduced":["0"],"last_affected":[],"package":"python-PyPDF2","purl":"pkg:rpm/opensuse/python-PyPDF2\u0026distro=openSUSE%20Leap%2015.6","source":"openSUSE-SU-2024:0366-1"}],"prev":{"headline":"Default redirect callback vulnerable to open redirects","id":"CVE-2022-24858"},"products":["PyPDF2"],"published":"2022-04-18","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"2025-04-22","vendors":["py-pdf"]},"summary":"An attacker can cause a denial of service via an infinite loop in PyPDF2 by crafting a malicious PDF with manipulated inline images.","url":"https://insights.sbomify.com/CVE-2022-24859/"}
