Hi,
The following vulnerability was published for libnet-oauth-perl.
CVE-2026-75589[0]:
| Net::OAuth versions before 0.33 for Perl check HMAC-SHA1, HMAC-
| SHA256 and PLAINTEXT signatures with a non-constant-time comparison
| in verify. Each of the three compares the signature carried in the
| message against the locally computed one with the eq operator, which
| returns as soon as the two strings differ. The time taken to reject
| a signature varies with the length of the matching prefix. RSA-SHA1
| is not affected, as it verifies through the RSA key object rather
| than by comparing strings. A client that can submit messages and
| time the replies may recover a valid signature one byte at a time
| rather than searching the whole signature space. Under PLAINTEXT the
| value compared against is the signature key itself, so the search
| recovers consumer_secret and token_secret.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Closes: 1144854 1144855
Changes:
libnet-oauth-perl (0.33-1) unstable; urgency=medium
.
* Import upstream version 0.33.
- Restrict the verification algorithm to those specified in the
allowed_signature_methods, which is now required. This is a breaking
change. (CVE-2026-72889)
(Closes: #1144854)
- HMAC_SHA1, HMAC_SHA256 and PLAINTEXT signature verification now use
constant-time comparison (CVE-2026-75589).
(Closes: #1144855)
- HMAC_SHA1 and HMAC_SHA256 signature keys cannot be blank.
* Add note about breaking change to debian/NEWS.Developer.
* debian/libnet-oauth-perl.docs: CONTRIBUTING.md is gone.
* Update years of upstream copyright.
* Update debian/upstream/metadata.
