RUSTSEC-2026-0348 Brotli certificate decompression can allocate up to 1 GiB before authentication

The built-in Brotli certificate decompressor enabled by the non-default brotli crate feature bounded the size of the decompressed output, but accepted a peer-selected history window. Brotli's large-window extension was enabled, so a five-byte header could cause an allocation of 1 GiB. A peer can...

RUSTSEC-2026-0347 Buffered application data sent to outer server after ECH rejection

When a server rejects Encrypted Client Hello ECH, the client completes the handshake using the outer ClientHello and authenticates the server against the ECH config's publicname. At the end of that handshake, rustls encrypted and queued any application data buffered via ClientConnection::writer...

RUSTSEC-2026-0349 Unauthenticated ServerHello can downgrade later connections to classical key exchange

The client recorded the server-selected key exchange group for each server name when processing the ServerHello, before the server was authenticated. This record is used to predict which key share to send in future ClientHellos to that server name. A network attacker can answer one connection...

RUSTSEC-2026-0346 `Debug` impls for client session values expose TLS secrets

The Debug implementations of Tls12ClientSessionValue and Tls13ClientSessionValue were derived, and so included the TLS 1.2 master secret or TLS 1.3 resumption PSK in their output. Custom ClientSessionStore implementations that format these values with Debug for example, when logging could disclos...

RUSTSEC-2026-0336 MIKEY message MAC is never verified on receive, so forged messages are accepted

mykey implements MIKEY RFC 3830 for SRTP key exchange. No receive path verified the MIKEY message authentication code. crypto::verifymac existed and was correct, but it was called only from unit tests — neither MikeyMessage::frombytes nor MikeyMessage::completepsk invoked it. newpskinit computed ...

RUSTSEC-2026-0337 Poly1305 panics or computes a wrong tag on attacker-chosen messages of 64 bytes or more

Poly1305 in ic-cipher absorbs messages of 64 bytes or more four blocks at a time, summing four products before one reduction. From 0.2.5 to 0.2.19 the reduction kept its carries in 32-bit integers, which four summed products can overflow when the message's bytes are large. This affects Poly1305 a...

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

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-2026-0312 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-2026-0307 `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-2026-0305 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-2026-0301 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-2026-0302 `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-2026-0293 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-2026-0304 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-2026-0306 `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...
