An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-40587 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- pyramid (PyPI): affected from 2.0.0; fixed in 2.0.2\n- pyramid (PyPI): affected from 2.0.0; fixed in 2.0.2\n- pyramid (PyPI): affected from 2.0.0; fixed in 2.0.2\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-2023-40587/ (Markdown: https://insights.sbomify.com/CVE-2023-40587/index.md)","id":"CVE-2023-40587","markdown":"https://insights.sbomify.com/CVE-2023-40587/index.md","name":"CVE-2023-40587","record":{"aliases":["DEBIAN-CVE-2023-40587","GHSA-j8g2-6fc7-q8f8","PYSEC-2026-1840","UBUNTU-CVE-2023-40587"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Python web framework","requires_auth":"none","summary":"Attackers can read index.html files one directory above static views in Pyramid when using specific Python versions and configurations.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"pyramid","vendor":"agendaless"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Pyramid is an open source Python web framework. A path traversal vulnerability in Pyramid versions 2.0.0 and 2.0.1 impacts users of Python 3.11 that are using a Pyramid static view with a full filesystem path and have a `index.html` file that is located exactly one directory above the location of the static view's file system path. No further path traversal exists, and the only file that could be disclosed accidentally is `index.html`. Pyramid version 2.0.2 rejects any path that contains a null-byte out of caution. While valid in directory/file names, we would strongly consider it a mistake to use null-bytes in naming files/directories. Secondly, Python 3.11, and 3.12 has fixed the underlying issue in `os.path.normpath` to no longer truncate on the first `0x00` found, returning the behavior to pre-3.11 Python, un an as of yet unreleased version. Fixes will be available in:Python 3.12.0rc2 and 3.11.5. Some workarounds are available. Use a version of Python 3 that is not affected, downgrade to Python 3.10 series temporarily, or wait until Python 3.11.5 is released and upgrade to the latest version of Python 3.11 series.","ecosystems":["PyPI"],"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":"Pyramid static view path traversal up one directory","id":"CVE-2023-40587","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"path_traversal","year":"2023"},"n_packages":3,"n_references":6,"next":{"headline":"Discourse DoS via 2FA and Security Key Names","id":"CVE-2023-40588"},"packages":[{"ecosystem":"PyPI","fixed":["2.0.2"],"introduced":["2.0.0"],"last_affected":[],"package":"pyramid","purl":null,"source":"GHSA-j8g2-6fc7-q8f8"},{"ecosystem":"PyPI","fixed":["2.0.2"],"introduced":["2.0.0"],"last_affected":[],"package":"pyramid","purl":"pkg:pypi/pyramid","source":"GHSA-j8g2-6fc7-q8f8"},{"ecosystem":"PyPI","fixed":["2.0.2"],"introduced":["2.0.0"],"last_affected":[],"package":"pyramid","purl":"pkg:pypi/pyramid","source":"PYSEC-2026-1840"}],"prev":{"headline":"go package github.com/corazawaf/coraza is vulnerable to denial of service","id":"CVE-2023-40586"},"products":["pyramid"],"published":"2023-08-25","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":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"2025-02-13","vendors":["Pylons"]},"summary":"Attackers can read index.html files one directory above static views in Pyramid when using specific Python versions and configurations.","url":"https://insights.sbomify.com/CVE-2023-40587/"}
