CVE Vulnerability Catalog

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.

A vulnerability in systemd causes systemd-coredump to ignore the kernel's fs.suid_dumpable setting, potentially leading to a local information leak.

CPAN.pm before version 2.35 does not verify TLS certificates when downloading distributions over HTTPS. This allows man-in-the-middle attackers to replace downloaded packages with malicious ones.

The pip package before version 19.2 for Python is vulnerable to directory traversal when a URL is provided in an install command. An attacker can exploit a Content-Disposition header containing '../' in the filename to overwrite files, such as /root/.ssh/authorized_keys.

A flaw in shadow-utils fails to properly clear the buffer when a new password is entered twice and the second attempt fails. This leaves the first password in memory, potentially allowing an attacker with sufficient access to retrieve it.

Vulnerability in CPAN 2.28 allows signature verification bypass. An attacker can supply unauthorized code that is treated as properly signed.

A vulnerability was found in systemd where a service using the DynamicUser property can create a SUID/SGID binary that remains executable with the transient service UID/GID even after the service terminates. A local attacker could exploit this to access resources owned by a potentially different UID/GID.

The KeyTrap vulnerability in the DNSSEC protocol allows a remote attacker to cause a Denial of Service (DoS) by sending DNSSEC responses containing many DNSKEY and RRSIG records. This leads to excessive CPU consumption on the DNS server, potentially causing overload.

The email module in Python through 3.11.3 incorrectly parses email addresses containing special characters. The wrong portion of an RFC2822 header is identified as the value of the addr-spec.

A vulnerability in Python 3.9.x before 3.9.16 and 3.10.x before 3.10.9 on Linux allows local privilege escalation in a non-default configuration. The multiprocessing library with the forkserver start method permits pickle deserialization from any user on the same local network of the machine.

It was discovered that a systemd service using the DynamicUser property can gain new privileges through the execution of SUID binaries, allowing creation of binaries owned by the service's transient group with the setgid bit set. A local attacker may exploit this flaw to access resources that will be.

A divide-by-zero error was discovered in py-lmdb 0.97 in the mdb_env_open2 function when mdb_env_read_header obtains a zero value for a certain size field. This issue can be triggered by supplying a crafted data.mdb file.

In GraphQL-Ruby before version 2.6.6, when using Execution::Next, authorization failures did not properly halt execution for fields using GraphQL::Schema::Resolver and its subclasses (including Mutation, RelayClassicMutation, and Subscription).

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.

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.

A flaw in GnuPG before version 2.2.18 allows certificate signature forgery using SHA-1 collision attacks. An attacker can create forged certificate signatures, compromising authentication integrity.

A vulnerability in the DNS protocol, related to the Closest Encloser Proof aspect in RFC 5155 (when RFC 9276 guidance is skipped), allows remote attackers to cause a denial of service (DoS) by triggering excessive CPU consumption for SHA-1 computations. The attack involves sending DNSSEC responses in a random subdomain attack, known as the NSEC3 issue.

A vulnerability in cross-origin redirect handling causes Proxy-Authorization and Proxy-Authenticate headers to persist, potentially leaking sensitive authentication data.

A vulnerability in the assembly implementation of an internal cryptographic function on the ppc64le architecture leaks a few bits of secret scalars due to the use of a variable-time instruction. Based on how this function is used, the leakage is not sufficient to recover the private key.

A vulnerability in the os package of the Go standard library allows improper access to the parent directory of an os.Root by opening a filename ending in "../". For example, Root.Open("../") opens the parent directory, bypassing access restrictions.
