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-2023-42452 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mastodon (Bitnami): affected from 4.0.0; fixed in 4.0.10, 4.1.8\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-2023-42452/ (Markdown: https://insights.sbomify.com/CVE-2023-42452/index.md)","id":"CVE-2023-42452","markdown":"https://insights.sbomify.com/CVE-2023-42452/index.md","name":"CVE-2023-42452","record":{"aliases":["BIT-mastodon-2023-42452","GHSA-2693-xr3m-jhqr"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Mastodon social network","requires_auth":"none","summary":"Attackers can inject malicious HTML via the translation feature, potentially executing scripts in victim browsers if CSP is bypassed.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"mastodon","vendor":"joinmastodon"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Mastodon is a free, open-source social network server based on ActivityPub. In versions on the 4.x branch prior to versions 4.0.10, 4.2.8, and 4.2.0-rc2, under certain conditions, attackers can abuse the translation feature to bypass the server-side HTML sanitization, allowing unescaped HTML to execute in the browser. The impact is limited thanks to Mastodon's strict Content Security Policy, blocking inline scripts, etc. However a CSP bypass or loophole could be exploited to execute malicious XSS. Furthermore, it requires user interaction, as this can only occur upon clicking the “Translate” button on a malicious post. Versions 4.0.10, 4.2.8, and 4.2.0-rc2 contain a patch for this issue.","ecosystems":["Bitnami"],"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":"Mastodon vulnerable to Stored XSS through the translation feature","id":"CVE-2023-42452","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"xss","year":"2023"},"n_packages":1,"n_references":2,"next":{"headline":"Improper validation of receipts allows forged read receipts in matrix synapse","id":"CVE-2023-42453"},"packages":[{"ecosystem":"Bitnami","fixed":["4.0.10","4.1.8"],"introduced":["4.0.0","4.1.0"],"last_affected":[],"package":"mastodon","purl":"pkg:bitnami/mastodon","source":"BIT-mastodon-2023-42452"}],"prev":{"headline":"Mastodon Invalid Domain Name Normalization vulnerability","id":"CVE-2023-42451"},"products":["mastodon"],"published":"2023-09-19","related":[{"cvss_score":10,"headline":"Mastodon vulnerable to arbitrary file creation through media attachments","id":"CVE-2023-36460","kev_date_added":null,"published":"2023-07-06"},{"cvss_score":9.8,"headline":"Improper Restriction of Excessive Authentication Attempts in mastodon/mastodon","id":"CVE-2022-2166","kev_date_added":null,"published":"2022-11-16"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2022-24307","kev_date_added":null,"published":"2022-02-03"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2018-21018","kev_date_added":null,"published":"2019-09-22"},{"cvss_score":9.4,"headline":"Mastodon Remote user impersonation and takeover","id":"CVE-2024-23832","kev_date_added":null,"published":"2024-02-01"},{"cvss_score":9.3,"headline":"Mastodon vulnerable to Cross-site Scripting through oEmbed preview cards","id":"CVE-2023-36459","kev_date_added":null,"published":"2023-07-06"},{"cvss_score":8.5,"headline":"Lack of media type verification of Activity Streams objects allows impersonation of remote accounts","id":"CVE-2024-25623","kev_date_added":null,"published":"2024-02-19"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-24","vendors":["mastodon"]},"summary":"Attackers can inject malicious HTML via the translation feature, potentially executing scripts in victim browsers if CSP is bypassed.","url":"https://insights.sbomify.com/CVE-2023-42452/"}
