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-2026-27742 in the wild and no public exploit code.\n\nAffected product: Bludit. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-27742/ (Markdown: https://insights.sbomify.com/CVE-2026-27742/index.md)","id":"CVE-2026-27742","markdown":"https://insights.sbomify.com/CVE-2026-27742/index.md","name":"CVE-2026-27742","record":{"aliases":["GHSA-wg93-hp69-vv5w"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Bludit CMS","requires_auth":"low_privilege","summary":"Authenticated users can inject JavaScript into post content, leading to session hijacking and content manipulation for other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"bludit","vendor":"bludit"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Bludit version 3.16.2 contains a stored cross-site scripting (XSS) vulnerability in the post content functionality.

An authenticated user can inject arbitrary JavaScript into the content field of a post, which is stored and later rendered to other users without proper output encoding. When viewed, the injected script executes in the context of the victim’s browser, allowing session hijacking, credential theft, content manipulation, or other actions within the user’s privileges.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Bludit \u003c= 3.16.2 Stored XSS in Post Content","id":"CVE-2026-27742","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"SPIP referer_spam \u003c 1.3.0 Unauthenticated SQL Injection","id":"CVE-2026-27743"},"packages":[],"prev":{"headline":"Bludit \u003c= 3.16.1 CSRF in Plugin and Theme Management Endpoints","id":"CVE-2026-27741"},"products":["Bludit"],"published":"2026-02-23","related":[{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2020-18879","kev_date_added":null,"published":"2021-08-20"},{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2020-20495","kev_date_added":null,"published":"2021-08-31"},{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2020-18190","kev_date_added":null,"published":"2020-10-02"},{"cvss_score":8.9,"headline":"Bludit - Remote Code Execution (RCE) through File API","id":"CVE-2024-24550","kev_date_added":null,"published":"2024-06-24"},{"cvss_score":8.9,"headline":"Bludit - Remote Code Execution (RCE) through Image API","id":"CVE-2024-24551","kev_date_added":null,"published":"2024-06-24"},{"cvss_score":8.8,"headline":"File upload in n/a","id":"CVE-2020-20210","kev_date_added":null,"published":"2023-06-26"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2023-31572","kev_date_added":null,"published":"2023-05-16"}],"sources":[{"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":"2026-07-14","vendors":["Bludit"]},"summary":"Authenticated users can inject JavaScript into post content, leading to session hijacking and content manipulation for other users.","url":"https://insights.sbomify.com/CVE-2026-27742/"}
