CVE Vulnerability Catalog

The email module in Python, specifically the BytesGenerator class, improperly quotes newlines in email headers during serialization, allowing header injection. This only affects usage of LiteralHeader that does not respect email folding.

The mongo-go-driver contains a heap out-of-bounds read vulnerability in the CGo implementation for GSSAPI (Kerberos) authentication on Linux and macOS. The issue arises from incorrect assumptions about string termination in the GSSAPI standard, potentially leading to data disclosure.

An improper initialization vulnerability in the AMD Secure Encrypted Virtualization (SEV) firmware allows an admin-privileged attacker to corrupt RMP-covered memory, potentially leading to loss of guest memory integrity.

The html.Parse function in the golang.org/x/net/html package enters an infinite loop when processing specially crafted HTML input. An attacker can exploit this vulnerability to cause a denial of service (DoS).

In the Linux kernel, the bnge driver has a vulnerability where a return statement is missing after auxiliary_device_uninit() in the error path. After auxiliary_device_add() fails, execution continues, potentially leading to use-after-free.

A use-after-free vulnerability was found in the QEMU LSI53C895A SCSI Host Bus Adapter emulation. This issue can lead to a crash or VM escape.

No description is available for CVE-2026-6502. The nature of the vulnerability cannot be determined.

The html.Parse function in golang.org/x/net/html has quadratic parsing complexity for specially crafted HTML inputs, which can lead to denial of service (DoS).

In PHP versions 8.3.x before 8.3.19 and 8.4.x before 8.4.5, a code sequence involving the __set handler or ??= operator and exceptions can lead to a use-after-free vulnerability.

In PHP versions 8.1.x before 8.1.31, 8.2.x before 8.2.26, 8.3.x before 8.3.14, uncontrolled long string inputs to the ldap_escape() function on 32-bit systems can cause an integer overflow, resulting in an out-of-bounds write.

Loofah's HTML5 sanitizer restricted only the xlink:href attribute on certain SVG elements to local, same-document references. Browsers also accept a plain href attribute as an alternative to the deprecated xlink:href per the SVG 2 spec, but Loofah did not apply the same restriction to it.

An issue in Axios 1.5.1 inadvertently reveals the confidential XSRF-TOKEN stored in cookies by including it in the HTTP header X-XSRF-TOKEN for every request made to any host, allowing attackers to view sensitive information.

Security advisory GHSA-2hw4-c9m4-f2fj concerns the knative/pkg component. Verification on 2026-05-19 confirmed end-to-end amplification of 4.5×, worse than the advisory's conservative 2× claim. A Go proof of concept (cmd/poc-c2/main.go) was built.
