High [CVE-2026-54572] Arbitrary file write via malicious symbolic link handling
Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.74.4, with -l/--links, rclone serializes symlinks as.rclonelink text objects and recreates them on a local destination without validating the target, allowing an attacker-controlled remote to plant an escaping symlink and cause a following object write to land outside the destination with attacker-chosen contents. This issue is fixed in version 1.74.4. A remote attacker could exploit this by providing a malicious symlink, allowing subsequent file writes to occur outside the intended destination with content chosen by the attacker. This could lead to unauthorized modification of files on the system. Rclone's -l/--links option serializes symbolic links encountered during a sync as `.rclonelink` text objects containing the link target, and later recreates those links on the destination. Prior to 1.74.4, rclone did not validate that a stored link target stays within the intended destination tree before recreating it. A remote storage backend under an attacker's control can therefore supply a crafted `.rclonelink` object whose target escapes the destination directory (e.g. via a `../` traversal or an absolute path), causing a subsequent write during the same or a later sync to be redirected outside the intended destination with attacker-chosen content.
High [CVE-2026-45363] Authentication bypass due to empty key in HMAC verification
ruby-jwt is a Ruby implementation of the RFC 7519 OAuth JSON Web Token standard. Prior to 2.10.3 and 3.2.0, JWT.decode(token, '', true, algorithm: 'HS256') accepts an attacker-forged token because OpenSSL::HMAC.digest('SHA256', '', payload) returns a valid digest under an empty key and no empty-key precondition exists in the HMAC algorithm. The same path is reached when a keyfinder block or key_finder: argument returns an empty string, nil, or an array containing nil for an unknown key, affecting HS256, HS384, and HS512 verification through JWT.decode and JWT::EncodedToken#verify_signature!. This issue is fixed in versions 2.10.3 and 3.2.0. A remote attacker can exploit this vulnerability by crafting a malicious token that is accepted due to an empty key being used in the HMAC (Hash-based Message Authentication Code) digest calculation during token verification. This allows the attacker to bypass authentication and integrity checks, potentially leading to unauthorized access or data manipulation. Red Hat severity: Important — CVSS 7.4 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N). Weakness: CWE-347. Affected Red Hat products: Red Hat Satellite 6.16 for RHEL 8; Red Hat Satellite 6.16 for RHEL 9; Red Hat Satellite 6.17 for RHEL 9; Red Hat Satellite 6.18 for RHEL 9; Red Hat Satellite 6.19 for RHEL 9; Red Hat Satellite 6.
High [CVE-2026-49477] Denial of Service via crafted CSS selector strings
Soup Sieve is a CSS selector library designed to be used with Beautiful Soup 4. Prior to 2.8.4, the CSS selector parser in soupsieve contains a regular expression vulnerable to catastrophic backtracking when processing an attribute selector with an unterminated quoted value in soupsieve/css_parser.py, allowing an attacker who can supply untrusted CSS selector strings to soupsieve.compile() or Beautiful Soup.select() /.select_one() to cause CPU exhaustion and denial of service. This issue is fixed in version 2.8.4. A remote attacker can exploit this by supplying a small, specially crafted CSS selector string to applications that process untrusted CSS, potentially blocking worker threads and causing a complete service denial in affected Red Hat products. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-1333.
