An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-47115 exists.\n\nAffected packages and fixed versions:\n- label-studio (PyPI): affected all versions; fixed in 1.9.2\n- label-studio (PyPI): affected all versions; fixed in 1.9.2\n- label-studio (PyPI): affected all versions; fixed in 1.9.2\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-2023-47115/ (Markdown: https://insights.sbomify.com/CVE-2023-47115/index.md)","id":"CVE-2023-47115","markdown":"https://insights.sbomify.com/CVE-2023-47115/index.md","name":"CVE-2023-47115","record":{"aliases":["GHSA-q68h-xwq5-mm7x","PYSEC-2024-126"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Data labeling tool","requires_auth":"none","summary":"Authenticated users can upload crafted images with HTML extensions to execute arbitrary JavaScript, potentially escalating privileges to administrator.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"label_studio","vendor":"humansignal"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Label Studio is an a popular open source data labeling tool. Versions prior to 1.9.2 have a cross-site scripting (XSS) vulnerability that could be exploited when an authenticated user uploads a crafted image file for their avatar that gets rendered as a HTML file on the website. Executing arbitrary JavaScript could result in an attacker performing malicious actions on Label Studio users if they visit the crafted avatar image. For an example, an attacker can craft a JavaScript payload that adds a new Django Super Administrator user if a Django administrator visits the image.\n\nThe file `users/functions.py` lines 18-49 show that the only verification check is that the file is an image by extracting the dimensions from the file. Label Studio serves avatar images using Django's built-in `serve` view, which is not secure for production use according to Django's documentation. The issue with the Django `serve` view is that it determines the `Content-Type` of the response by the file extension in the URL path. Therefore, an attacker can upload an image that contains malicious HTML code and name the file with a `.html` extension to be rendered as a HTML page. The only file extension validation is performed on the client-side, which can be easily bypassed.\n\nVersion 1.9.2 fixes this issue. Other remediation strategies include validating the file extension on the server side, not in client-side code; removing the use of Django's `serve` view and implement a secure controller for viewing uploaded avatar images; saving file content in the database rather than on the filesystem to mitigate against other file related vulnerabilities; and avoiding trusting user controlled inputs.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2023/CVE-2023-47115.yaml","stars":null,"title":"Label Studio - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":true,"headline":"Label Studio XSS Vulnerability on Avatar Upload","id":"CVE-2023-47115","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"xss","year":"2023"},"n_packages":3,"n_references":5,"next":{"headline":"Label Studio SSRF on Import Bypassing `SSRF_PROTECTION_ENABLED` Protections","id":"CVE-2023-47116"},"packages":[{"ecosystem":"PyPI","fixed":["1.9.2"],"introduced":["0"],"last_affected":[],"package":"label-studio","purl":null,"source":"GHSA-q68h-xwq5-mm7x"},{"ecosystem":"PyPI","fixed":["1.9.2"],"introduced":["0"],"last_affected":[],"package":"label-studio","purl":"pkg:pypi/label-studio","source":"GHSA-q68h-xwq5-mm7x"},{"ecosystem":"PyPI","fixed":["1.9.2"],"introduced":["0"],"last_affected":[],"package":"label-studio","purl":"pkg:pypi/label-studio","source":"PYSEC-2024-126"}],"prev":{"headline":"Ethyca Fides HTML Injection Vulnerability in HTML-Formatted DSR Packages","id":"CVE-2023-47114"},"products":["label-studio"],"published":"2024-01-23","related":[{"cvss_score":9.8,"headline":"Label Studio has Hardcoded Django `SECRET_KEY` that can be Abused to Forge Session Tokens","id":"CVE-2023-43791","kev_date_added":null,"published":"2023-11-09"},{"cvss_score":8.6,"headline":"Label Studio vulnerable to full account takeover by chaining Stored XSS + IDOR in User Profile via custom_hotkeys field","id":"CVE-2026-22033","kev_date_added":null,"published":"2026-01-12"},{"cvss_score":8.6,"headline":"Label Studio allows Server-Side Request Forgery in the S3 Storage Endpoint","id":"CVE-2025-25297","kev_date_added":null,"published":"2025-02-14"},{"cvss_score":7.6,"headline":"label-studio vulnerable to Cross-Site Scripting (Reflected) via the label_config parameter.","id":"CVE-2025-47783","kev_date_added":null,"published":"2025-05-14"},{"cvss_score":7.5,"headline":"Object Relational Mapper Leak Vulnerability in Filtering Task in Label Studio","id":"CVE-2023-47117","kev_date_added":null,"published":"2023-11-13"},{"cvss_score":6.1,"headline":"Label Studio allows Cross-Site Scripting (XSS) via GET request to `/projects/upload-example` endpoint","id":"CVE-2025-25296","kev_date_added":null,"published":"2025-02-14"}],"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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-30","vendors":["HumanSignal"]},"summary":"Authenticated users can upload crafted images with HTML extensions to execute arbitrary JavaScript, potentially escalating privileges to administrator.","url":"https://insights.sbomify.com/CVE-2023-47115/"}
