CWE-863

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In versions prior to 11.10.13, 12.6.7, and 12.10.2, a user disabled on a wiki using email verification for registration canouldre-activate themself by using the activation link provided for his registration. The problem has been patched in the following versions of XWiki: 11.10.13, 12.6.7, 12.10.2, 13.0. It is possible to workaround the issue by resetting the `validkey` property of the disabled XWiki users. This can be done by editing the user profile with object editor.

AMP Application Deployment Service in CubeCoders AMP 2.1.x before 2.1.1.2 allows a remote, authenticated user to open ports in the local system firewall by crafting an HTTP(S) request directly to the applicable API endpoint (despite not having permission to make changes to the system’s network configuration).

Bitcoin Core 0.12.0 through 0.21.1 does not properly implement the replacement policy specified in BIP125, which makes it easier for attackers to trigger a loss of funds, or a denial of service attack against downstream projects such as Lightning network nodes. An unconfirmed child transaction with nSequence = 0xff_ff_ff_ff, spending an unconfirmed parent with nSequence <= 0xff_ff_ff_fd, should be replaceable because there is inherited signaling by the child transaction. However, the actual PreChecks implementation does not enforce this. Instead, mempool rejects the replacement attempt of the unconfirmed child transaction.

kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel.

An issue was discovered in the AbuseFilter extension for MediaWiki through 1.35.2. A MediaWiki user who is partially blocked or was unsuccessfully blocked could bypass AbuseFilter and have their edits completed.

An issue was discovered in the AbuseFilter extension for MediaWiki through 1.35.2. It incorrectly executed certain rules related to blocking accounts after account creation. Such rules would allow for user accounts to be created while blocking only the IP address used to create an account (and not the user account itself). Such rules could also be used by a nefarious, unprivileged user to catalog and enumerate any number of IP addresses related to these account creations.
