Net::IMAP: Command Injection via non-synchronizing literal in "raw" argument

Several Net::IMAP commands accept a "raw data" argument that is sent verbatim after validation to prevent command injection. However, if a server does not support non-synchronizing literals, it may still be possible to inject arbitrary IMAP commands inside non-synchronizing literals. Details Raw...

OpenC3 COSMOS is Vulnerable to Self-XSS Through the Command Sender

Summary The Command Sender UI uses an unsafe eval function on array-like command parameters, which allows a user-supplied payload to execute in the browser when sending a command. This creates a self-XSS risk because an attacker can trigger their own script execution in the victim’s session, if...

Rack::Request accepts invalid Host characters, enabling host allowlist bypass

Summary Rack::Request parses the Host header using an AUTHORITY regular expression that accepts characters not permitted in RFC-compliant hostnames, including /, ?, , and @. Because req.host returns the full parsed value, applications that validate hosts using naive prefix or suffix checks can be...

Rack has quadratic complexity in Rack::Utils.select_best_encoding via wildcard Accept-Encoding header

Summary Rack::Utils.selectbestencoding processes Accept-Encoding values with quadratic time complexity when the header contains many wildcard entries. Because this method is used by Rack::Deflater to choose a response encoding, an unauthenticated attacker can send a single request with a crafted...

Rails Active Storage has possible content type bypass via metadata in direct uploads

Impact Active Storage's DirectUploadsController accepts arbitrary metadata from the client and persists it on the blob. Because internal flags like identified and analyzed are stored in the same metadata hash, a malicious direct-upload client could set these flags. Releases The fixed releases are...

Rails Active Storage has possible Path Traversal in DiskService

Impact Active Storage's DiskServicepathfor does not validate that the resolved filesystem path remains within the storage root directory. If a blob key containing path traversal sequences e.g. ../ is used, it could allow reading, writing, or deleting arbitrary files on the server. Blob keys are...

Rack's multipart parser buffers unbounded per-part headers, enabling DoS (memory exhaustion)

Summary Rack::Multipart::Parser can accumulate unbounded data when a multipart part’s header block never terminates with the required blank line CRLFCRLF. The parser keeps appending incoming bytes to memory without a size cap, allowing a remote attacker to exhaust memory and cause a denial of...

Google Sign-In for Rails allowed redirect to protocol-relative URI

Summary It is possible to redirect a user to another origin if the "proceedto" value in the session store is set to a protocol-relative URL. Details The googlesignin gem persists an optional URL for redirection after authentication. If this URL is set to a protocol-relative URL, it improperly...
