CVE-2026-67446 Mailpit: Thumbnail generation decodes unbounded image dimensions before scaling

Mailpit is an email testing tool and API for developers. Prior to 1.30.4, Mailpit decodes attacker-supplied image attachments into a full raster before checking decoded dimensions, pixel count, or memory use in the GET /api/v1/message/id/part/partID/thumb endpoint. The Thumbnail handler in...

CVE-2026-70653 libvips: Possible heap-based buffer read overflow when decoding a well-crafted RLE Radiance image

libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, the old-style Radiance RLE decoder in libvips/foreign/radiance.c can process a repeat marker at the beginning of a scanline in scanlinereadold and read q-1 before any prior pixel exists. A crafted Radiance...

AZL-96947 CVE-2026-63385 affecting package libevent for versions less than 2.1.13-1

Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has two HTTP parsing weaknesses in http.c. evhttpdecodeuriinternal decodes percent-encoded %00 bytes into literal NUL characters, which can cause downstream C string operations to truncate a path and bypass...

OSEC-2026-16 Path traversal in Cohttp.Path.resolve_local_file

The issue is that the function normalizes the URI path before percent decoding it: OCaml let resolvelocalfile docroot uri = let path = Uri.pctdecode path resolve "http" ofstring "/" uri in ... Because %2f is decoded after Uri.resolve, encoded separators survive dot-segment normalization. For...

CVE-2026-63385 Libevent: HTTP header handling bugs create risk of access control bypass.

Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has two HTTP parsing weaknesses in http.c. evhttpdecodeuriinternal decodes percent-encoded %00 bytes into literal NUL characters, which can cause downstream C string operations to truncate a path and bypass...

CVE-2026-63385

Libevent versions before 2.1.13 and 2.2.2-alpha contain two HTTP parsing flaws in http.c: evhttp_decode_uri_internal decodes %00 into literal NUL bytes, truncating paths to bypass validation; evhttp_header_is_valid_value accepts obsolete line folding with CRLF, enabling header injection and acces...

CVE-2026-63383

In libevent prior to 2.1.13 and 2.2.2-alpha, decode_tag_internal() in event_tagging.c requests at most five bytes via evbuffer_pullup but iterates over the full logical buffer length. A fragmented evbuffer holding a six-byte malformed tag can advance past the pullup window, causing an out-of-boun...

CVE-2026-63633

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A malicious Remote Desktop Protocol RDP server can exploit a heap buffer overflow vulnerability during Opus audio decoding. This occurs when the server negotiates Opus audio with a vulnerable client, causing the...

EUVD-2026-63469

SumatraPDF is a multi-format reader for Windows. In 3.6.1 and earlier, a crafted CHM file can supply malformed LZX Huffman code lengths to makedecodetable in ext/CHMLib/lzx.c. In the long-code branch, the function writes new internal nodes through nextsymbol before validating that the canonical...

github.com/labstack/echo: Echo: Unauthorized Information Disclosure via URL Path Decoding Discrepancy

A flaw was found in Echo, a Go web framework. An attacker can exploit a disagreement in URL path decoding between the router and the static file handler. The router processes raw encoded paths, while the static file handler unescapes encoded forward slashes. This allows an attacker to bypass...

USN-8653-1: PostgreSQL vulnerabilities

It was discovered that PostgreSQL incorrectly handled COPY FROM STDIN when an early failure occurred. An authenticated user could possibly use this issue to execute arbitrary SQL commands. CVE-2026-6464 It was discovered that PostgreSQL incorrectly reset extended statistics ownership during ALTER...

CVE-2026-73196 Ipa: freeipa: authenticated dos in `otptoken-add` via unbounded otp key decoding/re-encoding

A flaw was found in FreeIPA. A low-privilege authenticated user can exploit this vulnerability by submitting an oversized One-Time Password OTP key value. This oversized key is then decoded and re-encoded without proper size limits, consuming excessive CPU and memory resources. This can lead to a...
