CVE-2026-54332

gopacket provides packet processing capabilities for Go. In version 1.6.0 and earlier, the sFlow ExtendedGatewayFlow decoder in layers/sflow.go reads an attacker-controlled 32-bit community count and AS path member count and sizes a slice allocation from those counts without bounding them against...

CVE-2026-54635

pytonapi is a Python SDK for TONAPI that provides REST API, streaming, and webhook access to the TON blockchain. From 2.0.0 to 2.2.0, TonapiWebhookDispatcher fails to validate the Authorization header when a webhook handler is registered with the documented path argument, because setup stores...

CVE-2026-54635

CVE-2026-54635 affects pytonapi 2.0.0–2.2.0, where TonapiWebhookDispatcher fails to validate the Authorization header for webhook handlers registered with a documented path (custom path). The setup() logic only stores bearer tokens for default suffix paths, so self._tokens.get(path) returns None ...

SUSE CVE-2026-66037

FFmpeg through 8.1.2, fixed in commit 5d7112c, contains an uncontrolled resource consumption vulnerability in the IAMF demuxer that allows an unauthenticated attacker to cause multi-gigabyte memory allocation from a 17-byte input file by supplying a crafted countlabel field. The mixpresentationob...

CVE-2026-47180

A flaw was found in Zeroconf, a Python implementation of multicast DNS service discovery. An unauthenticated attacker on the local network can send a specially crafted multicast DNS mDNS packet with chained pointers. This can trigger a recursion error, leading to sustained CPU usage, excessive...

CVE-2026-47184

A flaw was found in Zeroconf, a Python library for multicast DNS service discovery. An unauthenticated attacker on the local network can send specially crafted multicast DNS responses. This can lead to uncontrolled memory growth, causing memory exhaustion and significantly degrading the performan...

GHSA-PP92-CRG2-GFV9 OAuth2::Client#request: Protocol-relative redirect Location overrides authority, leaking bearer Authorization to attacker host

Summary When an application uses OAuth2::Client typically via an OAuth2::AccessToken and the configured authorization server returns a redirect whose Location header is a protocol-relative URI of the form //attacker.example/leak, OAuth2::Clientrequest resolves the redirect with...

CVE-2026-54603 OAuth2::Client#request: Protocol-relative redirect Location overrides authority, leaking bearer Authorization to attacker host

OAuth2 is a Ruby wrapper for the OAuth 2.0 and 2.1 authorization frameworks, including OpenID Connect OIDC. From 0.4.0 to 2.0.21, a protocol-relative redirect Location returned to OAuth2::Clientrequest overrides the request authority, so the bearer Authorization header is sent to an...

CVE-2026-51303

A flaw was found in SQLite. A remote attacker can exploit a use-after-free vulnerability in the core parsing component by sending specially crafted SQL queries. This can lead to an application crash, sensitive information disclosure, and potentially allow the attacker to execute arbitrary code on...

GHSA-PRQ8-7WVH-44QH OAuth: Cross-origin token-request redirects can expose signed request metadata

Cross-origin OAuth token-request redirects can expose signed request metadata Summary When an application uses OAuth::Consumer to request OAuth 1.0 request tokens or access tokens, the token request helper follows 300..399 redirects returned by the OAuth server. In affected versions,...

gstreamer1-plugins-bad-free: GStreamer: Heap buffer overflow via crafted VNC server rectangle in librfb

A heap buffer overflow vulnerability was found in GStreamer's librfb RFB/VNC client. The rectangle bounds check incorrectly validates area rather than individual dimensions, allowing a malicious VNC server to send a rectangle that extends beyond the framebuffer. A remote attacker could set up a...

gstreamer1-plugins-bad-free: GStreamer: Signed integer overflow in VMnc decoder cursor payload handling

A signed integer overflow vulnerability was found in GStreamer's VMnc decoder. A crafted VMnc stream with large cursor dimensions can overflow signed integer payload-size arithmetic, bypassing a length check and leading to out-of-bounds reads. A remote attacker could trick a user into opening a...

gstreamer1-plugins-bad-free: GStreamer: Out-of-bounds read via JPEG segment length validation in VA decoder

An out-of-bounds read vulnerability was found in the VA JPEG decoder in GStreamer's gst-plugins-bad. The JPEG parser reads a segment length value from the bitstream without validating it against available data. A remote attacker could trick a user into opening a specially crafted JPEG file, causi...

GoPacket's sFlow ExtendedGatewayFlow decoder: unbounded attacker-controlled allocation (104-byte UDP datagram -> up to 16 GiB make) -> unauthenticated remote DoS

Summary The sFlow ExtendedGatewayFlow record decoder in github.com/gopacket/gopacket allocates a slice with makeuint32, n where n is an attacker-controlled 32-bit wire field that has no upper bound. Because the allocation happens before the read loop that would consume the corresponding bytes, a...

CVE-2026-51302

A flaw was found in SQLite. A use-after-free vulnerability in the expression evaluation logic, specifically within the sqlite3ReleaseTempReg and exprComputeOperands functions, allows a remote attacker to exploit the system. By supplying a malicious SQL statement, an attacker can cause a denial of...

CVE-2026-61609 Pterodactyl's shared global rate-limit key on login and 2FA checkpoint enables unauthenticated panel-wide authentication lockout (DoS)

Pterodactyl is a free, open-source game server management panel. From 1.7.0 until 1.13.0, the authentication rate limiter defined in RouteServiceProvider::configureRateLimiting applied a single global bucket to the login and two-factor checkpoint endpoints instead of keying by IP or account: the...
