Name constraints for URI names were incorrectly accepted

Name constraints for URI names were ignored and therefore accepted. Note this library does not provide an API for asserting URI names, and URI name constraints are otherwise not implemented. URI name constraints are now rejected unconditionally. Since name constraints are restrictions on otherwis...

Improperly masked return value from `table.grow` with Winch compiler backend

`unpack_in` can chmod arbitrary directories by following symlinks

In versions 0.4.44 and below of tar-rs, when unpacking a tar archive, the tar crate's unpackdir function uses fs::metadatafs-metadata to check whether a path that already exists is a directory. Because fs::metadata follows symbolic links, a crafted tarball containing a symlink entry followed by a...

Cache poisoning via insecure-by-default cache key

Pingora versions prior to 0.8.0 generated cache keys using only the URI path, excluding critical factors such as the host header. This allows an attacker to poison the cache and serve cross-origin responses to users. This vulnerability affects users of Pingora's alpha proxy caching feature who...

`time-sync` was removed from crates.io due to malicious code

The time-sync crate attempted to exfiltrate .env files to a server that was in turn impersonating the legitimate timeapi.io service. This the same attack that we've seen three times in the last few days. The malicious crate had 1 version published on 2026-03-04 approximately 50 minutes before...

`tracing_checks` was removed from crates.io for transitively including malicious code

This is part of an ongoing campaign to attempt to typosquat crates in an attempt to exfiltrate Polymarket credentials. The malicious crate had 1 version published on 2026-02-26 approximately 9 hours before removal and had no evidence of actual usage, both in terms of downloads and dependents. It...

ArrayQueue::push_front is not panic-safe

The safe API arrayqueue::ArrayQueue::pushfront can lead to deallocating uninitialized memory if a panic occurs while invoking the clone method on the passed argument. Specifically, pushfront receives an argument that is intended to be cloned and pushed, whose type implements the Clone trait...

Four unique double-free vulnerabilities triggered via safe APIs

The crate slice-ring-buffer was developed as a fork of slice-deque to continue maintenance and provide security patches, since the latter has been officially unmaintained RUSTSEC-2020-0158. While slice-ring-buffer has addressed some previously reported memory safety issues inherited from its fork...

surf is unmaintained

The developer has indicated that the crate is unmaintained. The last release is over three years old from 2021, the crate depends on the deprecated async-std crate and on a very old version of rustls for TLS support. Possible alternatives - reqwest - ureq...

Broadcast channel calls clone in parallel, but does not require `Sync`

The broadcast channel internally calls clone on the stored value when receiving it, and only requires T:Send. This means that using the broadcast channel with values that are Send but not Sync can trigger unsoundness if the clone implementation makes use of the value being !Sync. Thank you to...

Hickory DNS failure to verify self-signed RRSIG for DNSKEYs

Summary The DNSSEC validation routines treat entire RRsets of DNSKEY records as trusted once they have established trust in only one of the DNSKEYs. As a result, if a zone includes a DNSKEY with a public key that matches a configured trust anchor, all keys in that zone will be trusted to...

Ambiguous challenge derivation

Challenge derivation in non-interactive ZK proofs was ambiguous and that could lead to security vulnerability however, it's unknown if it could be exploited...

Unsoundness in `Iterator` and `DoubleEndedIterator` impls for `glib::VariantStrIter`

The VariantStrIter::implget function called internally by implementations of the Iterator and DoubleEndedIterator traits for this type was unsound, resulting in undefined behaviour. An immutable reference &p to a mut libc::cchar pointer initialized to NULL was passed as an argument to a C functio...

Delegate functions are missing `Send` bound

Affected versions of this crate did not require event handlers to have Send bound despite there being no guarantee of them being called on any particular thread, which can potentially lead to data races and undefined behavior. The flaw was corrected in commit afe3252 by adding Send bounds...

Improper validation of Windows paths could lead to directory traversal attack

towerhttp::services::fs::ServeDir didn't correctly validate Windows paths meaning paths like /foo/bar/c:/windows/web/screen/img101.png would be allowed and respond with the contents of c:/windows/web/screen/img101.png. Thus users could potentially read files anywhere on the filesystem. This only...

mozjpeg DecompressScanlines::read_scanlines is Unsound

This issue and vector is similar to RUSTSEC-2020-0029 of rgb crate which mozjpeg depends on. Affected versions of mozjpeg crate allow creating instances of any type T from bytes, and do not correctly constrain T to the types for which it is safe to do so. Examples of safety violation possible for...

Potential undefined behavior with Signature from a buffer-created BlameHunk

When a Blame is created via Blame::blamebuffer, and a BlameHunk is retrieved, the pointers to the original author, original committer, final author, and final committer may be null if unavailable. The corresponding BlameHunk methods then create Signatures based on null pointers; attempting to...

Potential undefined behavior when calling Remote::list()

When calling Remote::list for a remote of a git repository, when that remote does not advertise any references, git2 passes a null pointer to the unsafe function slice::fromrawparts. Based on the safety section documentation of function, data must be non-null even for slices of length zero. Thus,...

`Program<System>` accepts arbitrary executable programs

Affected versions of anchor-lang did not properly validate accounts declared as Program. The generic Program validation path used Pubkey::default as a sentinel to decide whether any executable program should be accepted. Since the system program id is also the default pubkey, Program was treated...

Denial of service in Steamworks game clients/servers using P2P authentication

Processing the raw ValidateAuthTicketResponset callback data panics when the meAuthSessionResponse field is kEAuthSessionResponseAuthTicketNetworkIdentityFailure. This can lead to denial of service in game clients and servers using the beginauthenticationsession API to authenticate players if a...

Signature Verification on AVX2 Platforms Mishandles Edge Case

The AVX2 implementation of ML-DSA verification incorrectly implemented the usehint function, mishandling an edge case that should lead to signature rejection. Impact An attacker could make the ML-DSA verifier accept a crafted invalid signature under a maliciously generated verification key, if th...

Buffer overflow in `Clusterings::from_i32_column_major_order()`

The fromi32columnmajororder method can create inconsistent internal state. When labels length and nitems mismatch, nclusterings becomes labels.len / nitems truncated, but subsequent calls to label use indices that exceed the internal data bounds, causing a buffer overflow. For example,...

NSEC3 closest-encloser proof validation enters unbounded loop on cross-zone responses

The NSEC3 closest-encloser proof validation in hickory-net's DnssecDnsHandle walks from the QNAME up to the SOA owner name, building a list of candidate encloser names. The iterator used assumes the QNAME is a descendant of the SOA owner, terminating only when the current candidate equals the SOA...

Improper check of an invariant resulting in incorrect bounds checks

A bounds verification of a slice storage of a 2-dimensional matrix's coefficients a kernel would compare the total size against the product of individual dimensions. This would erroneously cast after the multiplication and consequently fail to detect possible violations when overflow occurs...

Fragile bounds check when sampling from image

A read of pixels was coded as modifying coordinates to lie within the image bounds. It would calculate a coordinate by adding a constant to an input and taking the minimum of the resulting coordinate and 'dimension - 1'. This would not protect against malicious inputs that could overflow the...
