In RNP version 0.18.0 a refactoring regression causes the symmetric session key used for Public-Key Encrypted Session Key (PKESK) packets to be left uninitialized except for zeroing, resulting in it always being an all-zero byte array. Any data encrypted using public-key encryption in this release can be decrypted trivially by supplying an all-zero session key, fully compromising confidentiality. The vulnerability affects only public key encryption (PKESK packets).  Passphrase-based encryption (SKESK packets) is not affected. Root cause: Vulnerable session key buffer used in PKESK packet generation. The defect was introduced in commit `7bd9a8dc356aae756b40755be76d36205b6b161a` where initialization logic inside `encrypted_build_skesk()` only randomized the key for the SKESK path and omitted it for the PKESK path.Show less

The Hydra Booking — Appointment Scheduling & Booking Calendar plugin for WordPress is vulnerable to unauthorized booking cancellation in all versions up to, and including, 1.1.27. This is due to the plugin's "tfhb_meeting_form_submit_callback" function using insufficiently random values to generate booking cancellation tokens, combined with a globally shared nonce. This makes it possible for unauthenticated attackers to cancel arbitrary bookings via brute force attacks against the tfhb_meeting_form_cencel AJAX endpoint.Show less

The Banhammer – Monitor Site Traffic, Block Bad Users and Bots plugin for WordPress is vulnerable to Blocking Bypass in all versions up to, and including, 3.4.8. This is due to a site-wide “secret key” being deterministically generated from a constant character set using md5() and base64_encode() and then stored in the `banhammer_secret_key` option. This makes it possible for unauthenticated attackers to bypass the plugin’s logging and blocking by appending a GET parameter named `banhammer-process_{SECRET}` where `{SECRET}` is the predictable value, thereby causing Banhammer to abort its protections for that request.Show less

A vulnerability has been found in youth-is-as-pale-as-poetry e-learning 1.0. Impacted is the function encryptSecret of the file e-learning-master\exam-api\src\main\java\com\yf\exam\ability\shiro\jwt\JwtUtils.java of the component JWT Token Handler. The manipulation leads to insufficiently random values. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitability is considered difficult.

The PSW Front-end Login & Registration plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.12 via the customer_registration() function. This is due to the use of a weak, low-entropy OTP mechanism in the forget() function. This makes it possible for unauthenticated attackers to initiate a password reset for any user, including administrators, and elevate their privileges for full site takeover.Show less

A vulnerability, which was classified as problematic, was found in Tmall Demo up to 20250505. This affects an unknown part of the file /tmall/order/pay/ of the component Payment Identifier Handler. The manipulation leads to insufficiently random values. It is possible to initiate the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The vendor was contacted early about this disclosure but did not respond in any way.Show less

Undici is an HTTP/1.1 client. Starting in version 4.5.0 and prior to versions 5.28.5, 6.21.1, and 7.2.3, undici uses `Math.random()` to choose the boundary for a multipart/form-data request. It is known that the output of `Math.random()` can be predicted if several of its generated values are known. If there is a mechanism in an app that sends multipart requests to an attacker-controlled website, they can use this to leak the necessary values. Therefore, an attacker can tamper with the requests going to the backend APIs if certain conditions are met. This is fixed in versions 5.28.5, 6.21.1, and 7.2.3. As a workaround, do not issue multipart requests to attacker controlled servers.Show less

When batch jobs are executed by pgAgent, a script is created in a temporary directory and then executed. In versions of pgAgent prior to 4.2.3, an insufficiently seeded random number generator is used when generating the directory name, leading to the possibility for a local attacker to pre-create the directory and thus prevent pgAgent from executing jobs, disrupting scheduled tasks.Show less

The WPC Shop as a Customer for WooCommerce plugin for WordPress is vulnerable to account takeover and privilege escalation in all versions up to, and including, 1.2.8. This is due to the 'generate_key' function not producing a sufficiently random value. This makes it possible for authenticated attackers, with Subscriber-level access and above, to log in as site administrators, granted they have triggered the ajax_login() function which generates a unique key that can be used to log in.Show less
