CVE-2026-13576

UNKNOWN

Published 2026-10-30 · Source 9b29abf9-4ab0-4765-b253-1875cd9b441e

Description

CallBackery versions before 0.62.0 for Perl store user passwords as unsalted HMAC-SHA1 hashes. Passwords are hashed with hmac_sha1_sum() from Mojo::Util with no key, a single fast SHA-1 HMAC. There is no salt, so equal passwords give equal hashes, and no work factor slows down guessing. An attacker who obtains the user table can recover passwords by fast offline guessing.

CWE-759CWE-916

CVE-2026-87768
DateTime::Lite versions before 0.8.1 for Perl allow CPU exhaustion via a per-day loop when adding seconds. _normalize_leap_seconds crosses day boundaries one day at a time, so add(seconds => $n) on an object with a non-floating time zone takes about |$n|/86400 iterations, and nothing limits $n. The XS implementation and the pure-Perl fallback both have the loop. An attacker who controls the number of seconds added can keep the process busy for as long as they choose.

CVE-2026-119038
Business::GoCardless versions before 1.01 for Perl complete redirect flows without checking the session token, letting a leaked redirect flow ID create payments against another customer's mandate. confirm_resource takes no session token from the caller. It reads the redirect flow back from the GoCardless API and completes it with the token from that response, so the check that the flow is completed by the session that started it always passes. It then creates the requested payment or subscription against the flow's mandate. Since version 1.00, a flow that already has a mandate is returned as confirmed without being completed again, so the same ID creates a new payment on every call. A remote attacker who obtains another customer's redirect flow ID can create payments or subscriptions against that customer's mandate.

CVE-2026-119037
Business::GoCardless versions before 1.01 for Perl accept forged webhooks when a configured webhook secret is undef or empty. signature_valid uses each configured secret as the HMAC key, and nothing rejects undef or an empty string, both of which Digest::SHA treats as an empty key. A secret read from an unset environment variable, or an empty entry in a list of rotated secrets, is used as is. A remote attacker can sign a forged webhook with an empty key and have it accepted as sent by GoCardless.
