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-2026-115897/ (Markdown: https://insights.sbomify.com/CVE-2026-115897/index.md)","id":"CVE-2026-115897","markdown":"https://insights.sbomify.com/CVE-2026-115897/index.md","name":"CVE-2026-115897","record":{"aliases":["AZL-111404","CLSA-2026-1793180818","CLSA-2026-1793183866","CLSA-2026-1793187934","CLSA-2026-1793207115","CLSA-2026-1793209309","MINI-2vjf-2j3w-vqp3","MINI-6cxw-hpcm-65m5","MINI-7557-qw6m-7292","MINI-9p5j-3f6p-fc9c","MINI-qvgc-hw6f-r9xj","MINI-v2rc-3q4w-wg74"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"cvss":{"score":2.1,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:P/VC:L/VI:L/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":"Serialize JavaScript serializes JavaScript values to a superset of JSON that includes regular expressions and functions. Prior to 7.1.3, the function-source escaping logic does not neutralize a bare closing-script prefix when attacker-influenced function source text ends exactly at that prefix. Because each function body is escaped independently, a delimiter supplied by surrounding serialized output can terminate an HTML script element, and a later serialized value supplies injected markup that becomes a live element in the page. Exploitation requires control of a serialized function's source text, such as through a spoofed toString(). This issue is fixed in version 7.1.3.","ecosystems":[],"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":"Serialize JavaScript: Cross-site scripting (XSS) via unescaped \u003c/script at the end of a serialized function body","id":"CVE-2026-115897","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Topluyo Desktop for Linux has an OS Command Injection issue","id":"CVE-2026-115904"},"packages":[],"prev":{"headline":"Happy DOM: Incomplete fix for CVE-2026-33943: unsanitized import alias leads to host code execution","id":"CVE-2026-115895"},"products":["serialize-javascript"],"published":"2026-10-23","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-26","vendors":["yahoo"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-115897/"}
