An update that solves four vulnerabilities can now be installed.
## Description:
This update for python-PyJWT fixes the following issues
* CVE-2026-48522: `PyJWKClient` passes URI arguments directly to
`urllib.request.urlopen()` and allows for SSRF and token forgery
(bsc#1266798).
* CVE-2026-48523: verifier-side algorithm allow-list bypass when
`jwt.decode()` or `jwt.decode_complete()` are called with a PyJWK key
(bsc#1266799).
* CVE-2026-48525: unbounded Base64URL decoding of unused payload segment in
`b64=false` detached JWS allows for DoS (bsc#1266801).
* CVE-2026-48526: no validation of use of JSON Web Keys in HMAC algorithm when
decoding JSON Web Tokens allows for forged HS256 tokens (bsc#1266802).
