There are no new CVEs specific to jQuery 3.7.1 vulnerabilities — 3.7.1, released in August 2023, was a patch release that fixed a regression introduced in 3.7.0 involving Trusted Types support, not a security fix. The reason "jQuery 3.7.1 vulnerabilities" shows up as a search at all is that scanners frequently flag jQuery by version range, and most of the real security history sits several major versions earlier, in the 1.x and 3.4/3.5 releases. If your scanner is flagging jQuery 3.7.1 as vulnerable, it's almost certainly matching against an older CVE's affected-version range incorrectly, or it's flagging a transitive vendored copy elsewhere in the bundle rather than the version actually loaded at runtime.
What did jQuery 3.7.1 actually change, and are there real jQuery 3.7.1 vulnerabilities?
jQuery 3.7.1 fixed a bug where jQuery.htmlPrefilter broke under strict Trusted Types enforcement after the 3.7.0 release added Trusted Types compatibility as a feature, not a vulnerability fix. Trusted Types is a browser API designed to prevent DOM-based XSS by requiring that any string assigned to a dangerous sink (like innerHTML) be explicitly typed as safe, and jQuery 3.7.0 added support for sites that enforce that policy — a genuinely good security-adjacent change — but the initial implementation had an edge case that broke certain HTML-parsing code paths, which 3.7.1 corrected. That's a stability fix riding on top of a security-hardening feature, not a new vulnerability disclosure, and it's worth knowing the difference before treating every jQuery release note as a CVE.
What were the actual jQuery CVEs that matter?
The two jQuery vulnerabilities that show up most often in real scan results are CVE-2019-11358, a prototype pollution issue in $.extend() fixed in jQuery 3.4.0, and CVE-2020-11022 / CVE-2020-11023, cross-site scripting issues in jQuery()'s HTML parsing (specifically around .html(), .append(), and related methods processing untrusted strings containing <option> elements) fixed in jQuery 3.5.0. Both are old enough now that any application running jQuery 3.7.x is unaffected by them directly — the fixes have been in every release since 3.4.0 and 3.5.0 respectively — but they persist in scan reports because so much legacy code still bundles jQuery 1.x or 2.x, sometimes vendored inside a third-party plugin that nobody upgraded when the main application moved on.
Why do scanners keep flagging jQuery long after it's patched?
The most common cause is a mismatch between the declared dependency version and the actual bundled file — a package.json might list jQuery 3.7.1, while a vendored copy of jQuery 1.12 ships inside an unrelated UI plugin's dist folder and never gets deduplicated by the build. SCA scanning tools that only read manifest files miss this entirely; tools that fingerprint the actual JavaScript files present in a build catch it, because they're matching content hashes and code patterns against known-vulnerable versions rather than trusting whatever a package.json claims. The second common cause is scanners using overly broad version-range matching, where a CVE's "affected versions" field wasn't scoped tightly enough and ends up flagging a patched release as vulnerable — a known source of false positives across the jQuery ecosystem that's worth spot-checking manually before filing a ticket.
Is jQuery still worth using in a 2026 stack?
For projects that already depend on it, jQuery 3.7.x is a reasonably safe, actively maintained choice — the project still ships security patches and the maintainers have been conservative about the API surface that historically caused problems (the HTML-parsing sinks behind CVE-2020-11022/11023 got materially safer defaults in 3.5.0 onward). For new projects, the calculus is different: most modern frameworks don't need jQuery's DOM abstraction layer at all, and every dependency — however well-maintained — is still attack surface that has to be tracked, patched, and scanned. The pragmatic guidance for an existing codebase is to upgrade to the current 3.7.x release and stop there rather than remove jQuery outright, since a rewrite to eliminate a well-patched dependency is rarely worth the regression risk it introduces.
Either way, the version number alone tells you very little without checking what's actually bundled in a production build. A team running SCA scanning as part of its normal pipeline gets this check for free on every build, which matters more for jQuery specifically than for most dependencies, given how often it ends up vendored inside unrelated third-party plugins rather than declared as a direct dependency anyone remembers to update.
FAQ
Does jQuery 3.7.1 have any known unpatched CVEs?
No confirmed CVEs are outstanding against jQuery 3.7.1 as of this writing. Always check the current CVE feeds before assuming that stays true indefinitely, since new research can surface issues in any library.
Why does my scanner say jQuery 3.7.1 is vulnerable?
Check whether the flagged CVE's affected-version range was scoped correctly, and check whether an older, vendored copy of jQuery exists elsewhere in your build output alongside the declared 3.7.1 dependency.
What's the difference between jQuery 3.7.0 and 3.7.1?
3.7.0 added Trusted Types support; 3.7.1 fixed a regression that support introduced in htmlPrefilter. Neither release involved a new CVE.
Should I upgrade from jQuery 3.6 to 3.7.1?
Yes, if you're already on the 3.x line — it's a low-risk upgrade that picks up the Trusted Types compatibility fix and keeps you current with the maintained release.
