Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-32109 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- copyparty (PyPI): affected all versions; fixed in 1.20.12\n- copyparty (PyPI): affected all versions; fixed in 1.20.12\n- copyparty (PyPI): affected all versions; fixed in 1.20.12\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-2026-32109/ (Markdown: https://insights.sbomify.com/CVE-2026-32109/index.md)","id":"CVE-2026-32109","markdown":"https://insights.sbomify.com/CVE-2026-32109/index.md","name":"CVE-2026-32109","record":{"aliases":["GHSA-rcp6-88mm-9vgf","PYSEC-2026-32"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Copyparty file server","requires_auth":"low_privilege","summary":"An attacker with write access can upload a malicious file to execute arbitrary JavaScript in a victim's browser via a crafted URL.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"copyparty","vendor":"9001"}],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Copyparty is a portable file server. Prior to 1.20.12, if an attacker has been given both read- and write-permissions to the server, they can upload a malicious file with the filename .prologue.html and then craft a link to potentially execute arbitrary JavaScript in the victim's context. Note that it is intended behavior that the JavaScript would execute if the target clicks a link to the HTML file itself; \"https://example.com/foo/.prologue.html\". The vulnerability is that \"https://example.com/foo/?b\" would also evaluate the file, making the behavior unexpected. There are existing preventative measures (strict SameSite cookies) which makes it harder to leverage this vulnerability in an attack; in order to gain control of the target's authenticated session, the link must be clicked from a page served by the server itself -- most likely by editing an existing resource, which would require additional access permissions. Finally, for this attack to be successful, the attacker's target must click the specific crafted link given by the attacker. This vulnerability is not activated by normally browsing the web-UI on the server. This vulnerability is fixed in 1.20.12.","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":"Copyparty has unexpected JavaScript execution via crafted URL to folder with `.prologue.html`","id":"CVE-2026-32109","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"SiYuan has a Full-Read SSRF via /api/network/forwardProxy","id":"CVE-2026-32110"},"packages":[{"ecosystem":"PyPI","fixed":["1.20.12"],"introduced":["0"],"last_affected":[],"package":"copyparty","purl":null,"source":"GHSA-rcp6-88mm-9vgf"},{"ecosystem":"PyPI","fixed":["1.20.12"],"introduced":["0"],"last_affected":[],"package":"copyparty","purl":"pkg:pypi/copyparty","source":"GHSA-rcp6-88mm-9vgf"},{"ecosystem":"PyPI","fixed":["1.20.12"],"introduced":["0"],"last_affected":[],"package":"copyparty","purl":"pkg:pypi/copyparty","source":"PYSEC-2026-32"}],"prev":{"headline":"Copyparty ftp/sftp: Sharing a single file did not fully restrict source-folder access","id":"CVE-2026-32108"},"products":["copyparty"],"published":"2026-03-11","related":[{"cvss_score":7.8,"headline":"Cross-site scripting in n/a","id":"CVE-2023-41471","kev_date_added":null,"published":"2025-08-29"},{"cvss_score":7.5,"headline":"Copyparty is vulnerable to Regex Denial of Service (ReDoS) attacks through \"Recent Uploads\" page","id":"CVE-2025-54796","kev_date_added":null,"published":"2025-08-01"},{"cvss_score":7.5,"headline":"Path traversal in copyparty","id":"CVE-2023-37474","kev_date_added":null,"published":"2023-07-14"},{"cvss_score":6.3,"headline":"copyparty Reflected XSS via Filter Parameter","id":"CVE-2025-54589","kev_date_added":null,"published":"2025-07-31"},{"cvss_score":6.3,"headline":"copyparty vulnerable to reflected cross-site scripting via k304 parameter","id":"CVE-2023-38501","kev_date_added":null,"published":"2023-07-25"},{"cvss_score":5.4,"headline":"Copyparty vulnerable to eflected cross-site scripting via setck parameter","id":"CVE-2026-27948","kev_date_added":null,"published":"2026-02-26"},{"cvss_score":5.4,"headline":"copyparty has a DOM-Based XSS vulnerability when displaying multimedia metadata","id":"CVE-2025-54423","kev_date_added":null,"published":"2025-07-28"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-12","vendors":["9001"]},"summary":"An attacker with write access can upload a malicious file to execute arbitrary JavaScript in a victim's browser via a crafted URL.","url":"https://insights.sbomify.com/CVE-2026-32109/"}
