CVE-2019-10071
The code which checks HMAC in form submissions used String.equals() for comparisons, which results in a timing side channel for the comparison of the HMAC signatures. This could lead to remote code execution if an attacker is able to determine the correct signature for their payload. The comparison should be done with a constant time algorithm instead.

AnythingLLM is an application that turns pieces of content into context that any LLM can use as references during chatting. Prior to commit e287fab56089cf8fcea9ba579a3ecdeca0daa313, the password recovery endpoint returns different error messages depending on whether a username exists, so enabling username enumeration. Commit e287fab56089cf8fcea9ba579a3ecdeca0daa313 fixes this issue.
In the Twilio Authy API, accessed by Authy Android before 25.1.0 and Authy iOS before 26.1.0, an unauthenticated endpoint provided access to certain phone-number data, as exploited in the wild in June 2024. Specifically, the endpoint accepted a stream of requests containing phone numbers, and responded with information about whether each phone number was registered with Authy. (Authy accounts were not compromised, however.)
In Rhonabwy through 1.1.13, HMAC signature verification uses a strcmp function that is vulnerable to side-channel attacks, because it stops the comparison when the first difference is spotted in the two signatures. (The fix uses gnutls_memcmp, which has constant-time execution.)
php-jwt 1.0.0 uses strcmp (which is not constant time) to verify authentication, which makes it easier to bypass authentication via a timing side channel.
l8w8jwt 2.2.1 uses memcmp (which is not constant time) to verify authentication, which makes it easier to bypass authentication via a timing side channel.

The device has a webserver that exposes a REST API authenticated with a token on the management network. By exploiting an OS command injection vulnerability an authenticated attacker can send arbitrary commands to the device that are executed with administrative permissions by the underlying operating system.
GD versions before 2.86 for Perl allow OS command injection and file overwrite via a 2-arg open() of filename arguments in _make_filehandle. GD::Image::_make_filehandle opens a filename argument with Perl's 2-arg open(), so a filename that begins or ends with a pipe ("| cmd", "cmd |") or begins with a redirect ("> path", ">> path") is run as a command or redirect rather than opened as a file. _make_filehandle is the single open path behind every filename-accepting constructor (new, newFromPng, newFromJpeg, and the rest); the in-memory *Data variants do not open a path and are unaffected. Any caller that forwards untrusted input to one of these constructors as a pathname can run an arbitrary command or truncate a file under the process UID.
Nefteprodukttekhnika BUK TS-G Gas Station Automation System 2.9.1 through 2.10.2 on Linux contains an Improper Authentication vulnerability (CWE-287) in the system configuration module. The /php/ajax-login.php endpoint returns userid=1 (administrator) in response to any HTTP POST request that supplies arbitrary credentials (e.g., action=dologin&login=<any_value>&pwd=<any_value>), and subsequent privileged endpoints under /php/ajax-main.php and /modules/* do not validate a server-side session. A remote unauthenticated attacker can invoke any administrative action exposed by the configuration module, including reading and modifying user rules, fuel tank gauges, fuel dispensers, relays, cash registers, bank terminals, fuel cards, price and customer displays, cash collection, and pricing rules.
OpenClaw before 2026.5.27 contains a state mutation vulnerability in node pairing reconnection that allows paired nodes to confuse approval scope decisions. Attackers can exploit reconnection logic to restore or present broader node authority than intended, potentially bypassing approval restrictions.
A logic error in OAuthRequestFilter rejects legitimate requests originating from the bound IP address, while blindly allowing requests from any other IP address. Enabling this security feature inadvertently creates an inverse security check. Users are recommended to upgrade to versions 4.2.2 or 4.1.7, which fixes this issue.
