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-2020-26216 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- typo3fluid/fluid (Packagist): affected from 2.0.0; fixed in 2.0.8\n- typo3fluid/fluid (Packagist): affected from 2.0.0; fixed in 2.0.8\n- typo3fluid/fluid (Packagist): affected from 2.1.0; fixed in 2.1.7\n- typo3fluid/fluid (Packagist): affected from 2.1.0; fixed in 2.1.7\n- typo3fluid/fluid (Packagist): affected from 2.2.0; fixed in 2.2.4\n- typo3fluid/fluid (Packagist): affected from 2.2.0; fixed in 2.2.4\n- typo3fluid/fluid (Packagist): affected from 2.3.0; fixed in 2.3.7\n- typo3fluid/fluid (Packagist): affected from 2.3.0; fixed in 2.3.7\n- typo3fluid/fluid (Packagist): affected from 2.4.0; fixed in 2.4.4\n- typo3fluid/fluid (Packagist): affected from 2.4.0; fixed in 2.4.4\n- typo3fluid/fluid (Packagist): affected from 2.5.0; fixed in 2.5.11\n- typo3fluid/fluid (Packagist): affected from 2.5.0; fixed in 2.5.11\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-2020-26216/ (Markdown: https://insights.sbomify.com/CVE-2020-26216/index.md)","id":"CVE-2020-26216","markdown":"https://insights.sbomify.com/CVE-2020-26216/index.md","name":"CVE-2020-26216","record":{"aliases":["GHSA-hpjm-3ww5-6cpf"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 Fluid library","requires_auth":"none","summary":"Cross-site scripting vulnerabilities in TYPO3 Fluid allow attackers to inject malicious scripts via crafted attributes or unescaped content arguments.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"fluid","vendor":"typo3"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"TYPO3 Fluid before versions 2.0.8, 2.1.7, 2.2.4, 2.3.7, 2.4.4, 2.5.11 and 2.6.10 is vulnerable to Cross-Site Scripting. Three XSS vulnerabilities have been detected in Fluid: 1. TagBasedViewHelper allowed XSS through maliciously crafted additionalAttributes arrays by creating keys with attribute-closing quotes followed by HTML. When rendering such attributes, TagBuilder would not escape the keys. 2. ViewHelpers which used the CompileWithContentArgumentAndRenderStatic trait, and which declared escapeOutput = false, would receive the content argument in unescaped format. 3. Subclasses of AbstractConditionViewHelper would receive the then and else arguments in unescaped format.
