7.27.1→7.29.6@babel/core: Arbitrary File Read via sourceMappingURL Comment
CVE-2026-49356 / GHSA-4x5r-pxfx-6jf8
More information
Details
Impact
Using
@babel/coreto compile maliciously crafted code can allow ab attacker to read any source map from the system that is running Babel, if these conditions are all true:Users that only compile trusted code are not impacted.
Patches
The vulnerability has been fixed in
@babel/core@7.29.6and@babel/core@8.0.0-rc.6.Workarounds
Callers can mitigate the issue without upgrading by setting
inputSourceMap: falsein their Babel options.Callers can also manually extract the
#sourceMappingURLcomment from the input source code, validate whether the source map that it links to is allowed to be read, and if it is pass an object toinputSourceMap(passingfalsewhen it's not).Credits
Thanks Teodor-Cristian Radoi for reporting the vulnerability.
