CVE-2026-77560 Tinyauth: forward-auth per-app ACL is matched case-sensitively against the (case-insensitive) hostname, letting an authenticated user reach apps they are not on the allowlist for

Tinyauth is an authentication and authorization server. Prior to 5.1.2, Tinyauth compares forwarded hostnames case-sensitively while reverse proxies route equivalent hostnames case-insensitively, allowing an authenticated low-privilege user to bypass per-app access controls with a differently cas...

SUSE CVE-2026-91986

gitoxide gix-transport before 0.59.2 fails to filter control characters in git-daemon connect requests, allowing attackers to inject NUL/CR/LF bytes via crafted git URLs. Attackers can inject extra NUL-delimited protocol fields to spoof virtual hosts or inject newlines into daemon requests and lo...

io.netty/netty-codec-http: Netty: HTTP Request Smuggling due to control characters in the chunk-size line

A flaw was found in Netty. A remote attacker could exploit this by sending a specially crafted HTTP request that includes control characters within the chunk-size line. This bypasses the intended strict validation, allowing the attacker to inject arbitrary HTTP requests. This vulnerability can le...

org.jsoup/jsoup: jsoup: Cross-site scripting via malformed HTML tag names

A flaw was found in jsoup, a Java library for working with HTML. The HTML parser incorrectly handles malformed tag names ending in a control character. When a custom Safelist allows certain raw-text elements, this misparsing can cause content that should be inert to be processed as active markup...

io.netty/netty-codec-http: Netty RtspDecoder Method-Token Smuggling via Trailing Control Byte

A flaw was found in Netty RtspDecoder. The RtspMethods.valueOf function incorrectly strips trailing control bytes from method tokens in Real-Time Streaming Protocol RTSP requests. A remote attacker can exploit this by sending a specially crafted RTSP request, leading to method-token smuggling. Th...

PYSEC-2026-3988

Apache Airflow's /assets/events API returned asset events for every Dag in the deployment, with no filter restricting them to the Dags the caller is authorized to read. Any authenticated user holding asset-read access could therefore enumerate asset events — including the source Dag ID, task ID,...

CVE-2026-55625

GoCD , a continuous delivery server, is affected by an authorization bypass in its internal material connection test APIs (/go/api/admin/internal/material_test and /go/api/internal/config_repos/*/material_test) from version 16.1.0 through 26.1.0 . The APIs accept an arbitrary pipeline or pipeline...

CVE-2026-94394

When a regular user adds a reference between objects or attributes, MISP checks whether the user can access the overall event, but it does not always check whether the individual pieces of data are also allowed for that user. Because of this, someone who can view an event could potentially access...

libsoup: SoupWebsocketConnection: libsoup: WebSocket remote denial of service via oversized control frame protocol violation

A vulnerability was found in libsoup's WebSocket frame parsing implementation. The library fails to validate length rules specified in RFC 6455 §5.5, which mandates that all WebSocket control frames e.g., PING, PONG, CLOSE contain a payload of 125 bytes or less. A remote, unauthenticated attacker...

openssh: OpenSSH: sftp client allows attacker to control downloaded file location

A flaw was found in OpenSSH. The sftp client, when used to download files from a malicious server with the 'sftp server:/path .' command, does not properly restrict where those files are saved. This allows an attacker to control the download location, potentially overwriting existing files or...

CVE-2026-94394 MISP ObjectReferencesController: Granular Distribution and Sharing Group Restrictions Bypassed When Adding Object References

When a regular user adds a reference between objects or attributes, MISP checks whether the user can access the overall event, but it does not always check whether the individual pieces of data are also allowed for that user. Because of this, someone who can view an event could potentially access...

CVE-2026-94394

CVE-2026-94394 affects the MISP threat intelligence platform, specifically the ObjectReferencesController . When a regular user adds a reference between objects or attributes, MISP verifies access to the parent event but does not always enforce granular sharing group or distribution-level restric...

EUVD-2026-83911

When a user creates or edits a report inside an event, MISP can identify an existing report using its UUID without properly checking whether that report actually belongs to the same event. As a result, a user who has editing rights on one event could potentially move a report from another event...

io.netty/netty-codec-http: Netty: Security control bypass allows unauthorized requests via null origin header

A flaw was found in Netty, a network application framework. A remote attacker can bypass security controls in the CorsHandler component by sending a specially crafted request with a null origin header. This bypasses the intended access restrictions, allowing unauthorized requests to reach the...
