DoS in go-jose Parsing

CVE-2025-27144 / GHSA-c6gw-w398-hv78

More information

Details

Impact

When parsing compact JWS or JWE input, go-jose could use excessive memory. The code used strings.Split(token, ".") to split JWT tokens, which is vulnerable to excessive memory consumption when processing maliciously crafted tokens with a large number of '.' characters. An attacker could exploit this by sending numerous malformed tokens, leading to memory exhaustion and a Denial of Service.

Patches

Version 4.0.5 fixes this issue

Workarounds

Applications could pre-validate payloads passed to go-jose do not contain an excessive number of '.' characters.

Go JOSE Panics in JWE decryption

CVE-2026-34986 / GHSA-78h2-9frx-2jm8

More information

Details

Impact

Decrypting a JSON Web Encryption (JWE) object will panic if the alg field indicates a key wrapping algorithm (one ending in KW, with the exception of A128GCMKW, A192GCMKW, and A256GCMKW) and the encrypted_key field is empty. The panic happens when cipher.KeyUnwrap() in key_wrap.go attempts to allocate a slice with a zero or negative length based on the length of the encrypted_key.

This code path is reachable from ParseEncrypted() / ParseEncryptedJSON() / ParseEncryptedCompact() followed by Decrypt() on the resulting object. Note that the parse functions take a list of accepted key algorithms. If the accepted key algorithms do not include any key wrapping algorithms, parsing will fail and the application will be unaffected.

This panic is also reachable by calling cipher.KeyUnwrap() directly with any ciphertext parameter less than 16 bytes long, but calling this function directly is less common.

Panics can lead to denial of service.

Fixed In

4.1.4 and v3.0.5

Workarounds

If the list of keyAlgorithms passed to ParseEncrypted() / ParseEncryptedJSON() / ParseEncryptedCompact() does not include key wrapping algorithms (those ending in KW), your application is unaffected.

If your application uses key wrapping, you can prevalidate to the JWE objects to ensure the encrypted_key field is nonempty. If your application accepts JWE Compact Serialization, apply that validation to the corresponding field of that serialization (the data between the first and second .).

Release Notes

go-jose/go-jose (github.com/go-jose/go-jose/v4)

v4.1.4

Compare Source

What's Changed

Fixes Panic in JWE decryption. See GHSA-78h2-9frx-2jm8

Full Changelog: go-jose/go-jose@v4.1.3...v4.1.4

v4.1.3

Compare Source

This release drops Go 1.23 support as that Go release is no longer supported. With that, we can drop x/crypto and no longer have any external dependencies in go-jose outside of the standard library!

This release fixes a bug where a critical b64 header was ignored if in an unprotected header. It is now rejected instead of ignored.

What's Changed

• Remove Go 1.23 support by @​mcpherrinm in #​205
• Reject JWS with an unprotected critical b64 header by @​mcpherrinm in #​210

Full Changelog: go-jose/go-jose@v4.1.2...v4.1.3
