RUSTSEC-2026-0333 Resource budgets not enforced on the typed deserialization path

ParserConfig::maxevents, maxnodes, maxtotalscalarbytes, maxmergekeys, aliasanchorratio and the alias jump factor were enforced only by the two Value loaders. A typed target with a default-shaped configuration is served by the streaming deserializer, which never read those fields, so tightening an...

RUSTSEC-2026-0444 `astral-tl` is unmaintained

Astral deprecated astral-tl on October 5, 2026. All versions of the crate are unmaintained. For HTML parsing, Astral recommends astral-html as a replacement. astral-html: https://crates.io/crates/astral-html...

RUSTSEC-2026-0441 `pin-utils` is unmaintained

The upstream repository was archived on October 1, 2026, after the release of version 0.1.1. For local pinning, replace pinmut! with core::pin::pin!, available since Rust 1.68. For pin projection, replace unsafepinned! and unsafeunpinned! with pin-project or pin-project-lite. upstream repository:...

RUSTSEC-2026-0317 A 512-byte workbook can provoke a multi-gigabyte allocation and abort the process

Affected versions passed caller-supplied bytes to calamine's Xlsx::new without first checking that they were a ZIP archive. Xlsx::new tests for password protection on its first line, which parses the input as an OLE/CFB container, and a sector-count field read from the file's own header reaches...

RUSTSEC-2026-0330 Hybrid Encapsulation from Seed Panics on Short Seed

For a hybrid KEM public key of type PublicKey::WingKemDraft06 or PublicKey::X25519MlKem768Draft06, the PublicKey::encapsulatederand function would panic in an indexing operation on a seed input of length shorter than 32 bytes. Impact Applications encapsulating with an attacker controlled seed val...

RUSTSEC-2026-0311 Stack overflow on deeply nested LaTeX input

The parser and layout engine in affected versions of latex-rust recurse once per level of nesting with no limit. Deeply nested input, such as \frac1…, braces, \sqrt…, \left, or superscripts nested hundreds or thousands of levels deep, exhausts the call stack. A stack overflow in Rust aborts the...

RUSTSEC-2026-0310 Various panics, soundness and resource exhaustion issues

Version 0.12.3 fixes a large number of panics, soundness issues, and CPU and memory exhaustion issues in all parts of the crate. The following is a summary of the issues per affected components. For details, please see the release notes. Base Limited the number of compression pointers that are...

RUSTSEC-2026-0312 Excluded iPAddress name constraints with an all-zero mask are not applied

An excludedsubtrees iPAddress name constraint with an all-zero mask 0.0.0.0/0 or ::/0 does not restrict iPAddress SANs in certificates issued beneath it. The mask check treated an all-zero mask as matching nothing, when a /0 prefix matches every address of its family, so the exclusion was silentl...

RUSTSEC-2026-0308 Use-after-free in interned values and cached function results

When an application reads an interned value's fields or uses that value as an input to a tracked function, Salsa must ensure that reusable storage has been validated for the current database revision. This prevents the value's fields and associated cached function results from being freed while i...

RUSTSEC-2026-0305 Use-after-free when XML includes have duplicated entities

Librsvg uses libxml2, a C library, to parse XML. When librsvg parses an SVG document which has a nested Xinclude, an XML entity declaration with a duplicate name as an existing one can cause a use-after-free error. While libxml2 is expanding an internal entity, a recursive XInclude can parse...

RUSTSEC-2026-0307 `uncbv`: archive extraction is vulnerable to path traversal (zip-slip)

Summary uncbv extract writes each archive entry to outputdir.joinentryfilename using the filename stored in the archive with no check for .. components or absolute paths. A malicious .cbv / .cbz archive whose entry name contains ../ or an absolute path can therefore cause files to be written...

RUSTSEC-2026-0301 Double free in `StackVec::retain` when a predicate or element `Drop` panics

Summary StackVec::retain committed its new length to self.len only after its internal loop completed. If the retain predicate or a removed element's Drop implementation panicked before the loop finished, unwinding proceeded with self.len still equal to the original, pre-retain length, leaving...

RUSTSEC-2026-0303 `stack-graphs` is archived and unmaintained

The upstream repository github/stack-graphs has been archived. Issues and pull requests are disabled, so maintainers cannot be reached there. The last crates.io release is 0.14.1 2024-12-13. The repository's last push was 2025-09-09. There is no published successor...

RUSTSEC-2026-0302 `stack-graphs` C API exports are safe `extern "C"` functions

stackgraphs::c is a public module. From 0.0.3 through the current crates.io release 0.14.1, its pointer-taking entry points are pub extern "C" fn rather than unsafe fn. Safe Rust can call them. sgstackgraphfree frees the pointer with Box::fromraw. sgstackgraphfreestd::ptr::nullmut is immediate...

RUSTSEC-2026-0296 `unzip` is unmaintained

The unzip crate has only ever released a single version, 0.1.0 published 2017-12-23, and has seen no further activity. It appears to be unmaintained, and its known path-traversal "zip-slip" vulnerability will not be fixed. Consider migrating to an actively maintained alternative such as zip...

RUSTSEC-2026-0304 Finished streaming calls keep reading a stalled request body indefinitely

Affected versions of connectrpc start a background task to read the request body of every client-streaming and bidirectional-streaming call, before the interceptors or the handler run. A call can finish before it has consumed its request: the handler can return without reading all of its request...

RUSTSEC-2026-0293 Double free / use-after-free in `Consumer::skip` and `Consumer::clear` when an element's `Drop` panics

Consumer::skip and Consumer::clear are not panic-safe. They drop the consumed elements in place and only afterwards call advancereadindex to move the ring buffer's read index past them. If an element's Drop panics mid-loop, advancereadindex is never reached, so the read index still points at the...

RUSTSEC-2026-0306 `hex_decode_unchecked` AVX2 path reads past `src`

fasterhex::hexdecodeunchecked is a safe function. On x86 and x8664, when AVX2 is enabled, hexdecodeavx2 keeps decoding while dst.len = 32 and then loads 32 bytes from src and 32 bytes from src32... Nothing in that loop requires src to contain 64 bytes. A safe caller can pass a short src and a dst...

RUSTSEC-2026-0309 `SinglyLinkedList::remove` dereferences a null link

In versions before 0.2.1, SinglyLinkedList::remove is safe and walks the intrusive list with an unchecked dereference. On an empty list, or when node is not in the list, currentelm.next reads a null pointer. That is undefined behavior. The list head is a raw mut Node, and safe code can construct...

RUSTSEC-2026-0328 `decompress`: tar-family extractors write archive entries without a path-traversal check (tar-slip)

The tar-family extractors in decompress .tar, .tar.gz, .tar.xz, .tar.bz2, .tar.zst build each output path from the raw archive entry path and write to it with no traversal check, so a malicious archive can write files outside the destination directory, a "tar-slip" / zip-slip path traversal CWE-2...

RUSTSEC-2026-0294 Unsoundness in UTF-8 'String' trait

The String API in iceoryx2-bb-container exposes its contents as mutable bytes through safe APIs, while String::asstr converts those bytes into a Rust string slice without validating UTF-8. An application can therefore create an invalid &str and trigger undefined behavior using entirely safe Rust...

RUSTSEC-2026-0289 pqc_kyber is unmaintained

The crate has had no releases since 0.7.1 2023-08-23, and the upstream repository shows no maintainer activity.

RUSTSEC-2026-0287 cosmian_kyber is unmaintained

cosmiankyber is a fork of Argyle-Software/kyber that has seen no maintainer activity. It inherits the fork parent's broken AVX2 constant-time code, and the open fix pull request Cosmian/kyber6 has gone unanswered. Recommended alternatives: - aws-lc-rs - graviola...

RUSTSEC-2026-0286 Out-of-bounds read when decoding CKA_ALLOWED_MECHANISMS

cryptoki treated the CKAALLOWEDMECHANISMS ulValueLen byte count as a CKMECHANISMTYPE element count. A valid nonempty attribute returned through the safe Session::getattributes API could cause construction of an out-of-bounds slice and undefined behavior. Possible consequences include a process...

RUSTSEC-2026-0340 Peer minimum ACK delay can panic quinn-proto when ACK_FREQUENCY transmission is enabled

When sending ACKFREQUENCY frames is enabled through TransportConfig::ackfrequencyconfigSome.., the peer's transport parameters could cause AckFrequencyState::candidatemaxackdelay to call Duration::clamp with a minimum greater than its maximum, which panics. For example, a peer advertising a...

RUSTSEC-2026-0343 Outgoing datagram buffer accounting can panic the sender in quinn-proto

The limit on memory used to buffer outgoing datagrams, introduced in 0.11.17, subtracted an evicted datagram's size from the buffered byte counter twice when Datagrams::send was called with drop = true as Connection::senddatagram in the quinn crate does while the buffer was full. Under sustained...

RUSTSEC-2026-0338 Remote peer can panic quinn-proto with zero-length STREAM frames during unordered reads

When a stream is read in unordered mode for example through RecvStream::readfalse in quinn-proto or readunordered in quinn, quinn-proto proactively deduplicates received data by recording received ranges in a RangeSet through its replace method. When an incoming STREAM frame carried an empty...

RUSTSEC-2026-0285 TLS 1.3 handshake messages incorrectly accepted across encryption level boundaries

Rustls accepted TLS 1.3 handshake messages sent at the wrong encryption level when they followed a key-changing message in the same record. For example, a plaintext EncryptedExtensions message packed into the same record as the ServerHello was accepted. RFC 8446 section 5.1 requires that handshak...

RUSTSEC-2026-0298 Use-after-free when a future's `Drop` panics while the container is dropped

Storage::clear walks the slab, empties each entry and frees the Task allocation once its reference count reaches zero. self.tasks.setlen0 only runs after the loop. Emptying an entry drops the user future it holds, and T carries no bounds excluding a panicking Drop. If one unwinds, the length is...

RUSTSEC-2026-0282 Double free in `AlignedBox<[T]>::realloc_with_default` when an element's `Drop` panics

Shrinking an AlignedBox takes ownership of the buffer out of self.container with ManuallyDrop::take, destroys the elements past the new length, and only then commits the new Box back into self.container. ManuallyDrop::take moves ownership but not the bits, so until that commit self.container stil...

RUSTSEC-2026-0291 Double free in `OwnedAlloc::drop_in_place` when the contained value's `Drop` panics

OwnedAlloc::dropinplace destroys the contained value by hand, then commits the ownership transfer with mem::forgetself — which lives inside intoraw and so runs only after the destruction. T::drop is user code and may panic. If it does, the forget is skipped and the still-live OwnedAlloc unwinds,...

RUSTSEC-2026-0297 `unzip`: archive extraction is vulnerable to path traversal (zip-slip)

Summary Unzipper::unzip extracts each archive entry to a path built from the entry's raw, attacker-controlled name without any traversal check. A ZIP archive whose entry names contain ../ components or an absolute path can therefore cause files to be written outside the destination directory chos...

RUSTSEC-2026-0332 `WaveFormat::parse` reads past the end of a `&WAVEFORMATEX`

WaveFormat::parse is a safe function that takes a &WAVEFORMATEX, which is only valid for reads of sizeof:: 18 bytes. When the header has wFormatTag == WAVEFORMATEXTENSIBLE and cbSize = 22, the function reinterprets the reference as a WAVEFORMATEXTENSIBLE and reads 40 bytes. Nothing in the signatu...
