# CVE-2025-14524: bearer token leak on cross-protocol redirect

## TL;DR
bearer token leak on cross-protocol redirect

## Key Points
- cve / CVE-2025-14524 / CURL-CVE-2025-14524 / severity:Low / https://github.com/curl/curl / GIT

## Details
**Severity:** Low
**Advisory:** CURL-CVE-2025-14524 (CVE-2025-14524)

**Affected (your watchlist):**
- `GIT:https://github.com/curl/curl` curl-8_9_1 → no fixed version listed [mac]

**Details:**
When an OAuth2 bearer token is used for an HTTP(S) transfer, and that transfer
performs a cross-protocol redirect to a second URL that uses an IMAP, LDAP,
POP3 or SMTP scheme, curl might wrongly pass on the bearer token to the new
target host.
