Security Advisories (7)
CPANSA-Mojolicious-2022-03 (2022-12-10)

Mojo::DOM did not correctly parse <script> tags.

CPANSA-Mojolicious-2021-02 (2021-06-01)

Small sessions could be used as part of a brute-force attack to decode the session secret.

CVE-2021-47208 (2021-03-16)

A bug in format detection can potentially be exploited for a DoS attack.

CPANSA-Mojolicious-2018-04 (2018-08-09)

This release reverts the addition of stream classes (added in 7.83), which have unfortunately resulted in many Mojolicious applications becoming unstable. While there are no known exploits yet, we've chosen to err on the side of cautiousness and will classify this as a security issue.

CVE-2020-36829 (2020-11-10)

Mojo::Util secure_compare can leak the string length. By immediately returning when the two strings are not the same length, the function allows an attacker to guess the length of the secret string using timing attacks.

CVE-2024-58134 (2025-05-03)

Mojolicious versions from 0.999922 for Perl uses a hard coded string, or the application's class name, as an HMAC session cookie secret by default. These predictable default secrets can be exploited by an attacker to forge session cookies.  An attacker who knows or guesses the secret could compute valid HMAC signatures for the session cookie, allowing them to tamper with or hijack another user’s session.

CVE-2024-58135 (2025-05-03)

Mojolicious versions from 7.28 for Perl will generate weak HMAC session cookie secrets via "mojo generate app" by default When creating a default app skeleton with the "mojo generate app" tool, a weak secret is written to the application's configuration file using the insecure rand() function, and used for authenticating and protecting the integrity of the application's sessions. This may allow an attacker to brute force the application's session keys.
