Low [CVE-2026-17072] 4-byte heap over-read in gst_matroska_parse_flac_stream_headers when parsing FLAC codec data in Matroska containers
A flaw was found in GStreamer's gst-plugins-good. A heap-based out-of-bounds read of 4 bytes can occur when parsing FLAC audio stream headers embedded in a Matroska or WebM container file. The vulnerability is triggered by a boundary check that does not account for the full size of the data being copied, allowing a small read past the end of the allocated buffer. An attacker could exploit this by crafting a malicious Matroska or WebM file and tricking a user into opening it, potentially leaking a small amount of adjacent heap memory. This vulnerability is rated as Low severity because the out-of-bounds read is limited to 4 bytes, is read-only (no memory corruption), and the read cannot be directly observed or controlled by a remote attacker. User interaction is required to trigger it, as a victim must open a crafted Matroska or WebM media file. In practice, modern heap allocators align allocations such that the 4 overread bytes typically fall within adjacent allocated memory, making a crash unlikely in production builds. Red Hat Enterprise Linux 8, 9, 10, and Red Hat In-Vehicle OS 2 ship gstreamer1-plugins-good with the affected Matroska demuxer code path and are affected. All RHEL and RHIVOS streams are deferred (low severity, low exploitability). Red Hat severity: Low — CVSS 3.3 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N). Weakness: CWE-125.
Low [CVE-2026-64647] Information disclosure via server-side request caching
Next.js is a React framework for building full-stack web applications. In versions 12.0.0 through 15.5.20 and 16.0.0 through 16.2.10, a server-side fetch with a request body may return a cached response body from a different request to the same URL but different body. Confidential data in the POST's response body would then leak to unauthorized requests. Though the request itself will not be deduped. This is only an issue when receiving request bodies with a content type charset other than UTF-8. For example, the UTF-16 byte sequences for 삃삃 and 섄섄 in the request body would share the same cache. This issue has been fixed in versions 15.5.21 and 16.2.11. A flaw was found in Next.js. This vulnerability allows a remote attacker to potentially access confidential data. This can lead to the unauthorized disclosure of sensitive information. This Low impact information disclosure flaw affects Next.js applications where server-side fetches handle request bodies with non-UTF-8 charsets. Under these specific conditions, cached responses containing confidential data could be inadvertently exposed to unauthorized requests. Red Hat severity: Low — CVSS 3.7 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N). Weakness: CWE-524.
