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-2026-32773 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.spark:spark-core_2.12 (Maven): affected from 3.0.0; fixed in 3.5.8\n- org.apache.spark:spark-core_2.12 (Maven): affected from 3.0.0; fixed in 3.5.8\n- spark (Bitnami): affected from 3.0.0; fixed in 3.5.8\n- org.apache.spark:spark-core_2.13 (Maven): affected from 3.0.0; fixed in 3.5.8\n- org.apache.spark:spark-core_2.13 (Maven): affected from 3.0.0; fixed in 3.5.8\n- pyspark (PyPI): affected from 3.0.0; fixed in 3.5.8\n- pyspark (PyPI): affected from 3.0.0; fixed in 3.5.8\n- pyspark (PyPI): affected from 3.0.0; fixed in 3.5.8\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-2026-32773/ (Markdown: https://insights.sbomify.com/CVE-2026-32773/index.md)","id":"CVE-2026-32773","markdown":"https://insights.sbomify.com/CVE-2026-32773/index.md","name":"CVE-2026-32773","record":{"aliases":["BIT-spark-2026-32773","GHSA-9437-39hj-3c93","MINI-c695-7r4p-j8mq","MINI-h6vp-4c5q-qj39","MINI-m3j8-w53h-jp2j","PYSEC-2026-3966"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Spark","requires_auth":"none","summary":"Attackers with job submission rights can inject scripts into the Spark History Server, potentially escalating privileges in the victim's browser.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"spark","vendor":"apache"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","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-80","name":"Improper Neutralization of Script-Related HTML Tags in a Web Page"}],"description":"There is a lack of XSS escaping in the Spark History Server prior to 3.5.8 which allows a malicious Spark job to generate arbitrary unescaped frontend code which could lead to a minimal privilege escalation in browser.
