Coraza: jsDecode Off-by-One in Octal Escape Handling Enables WAF Bypass

Summary The t:jsDecode transformation in Coraza WAF contains an off-by-one error when parsing octal escape sequences. A backslash character was incorrectly included in the octal number buffer, causing strconv.ParseInt to fail for every octal escape sequence and return a null byte instead of the...

Coraza JSON body processor: argument-limit truncation reopens an unbounded-depth gjson.Valid stack overflow (process crash)

Summary The JSON body processor internal/bodyprocessors/json.go can be made to crash the whole process with an unrecoverable fatal error: stack overflow, using a request body that is well under the recommended SecRequestBodyLimit and the default SecArgumentsLimit. Root cause readJSON...

Coraza body processor has a JSON key collision that allows unauthenticated attackers to bypass OWASP CRS inspection

Summary Coraza's JSON body processor converts nested JSON properties into dot-separated ARGSPOST names without escaping dots contained in literal property names. Two distinct JSON properties can therefore collapse into the same Coraza variable An unauthenticated attacker can place a malicious val...

JHipster: Generated Applications Allow Stored XSS via Unrestricted Blob ContentType Opened as Same-Origin Blob

Summary Applications generated by generator-jhipster v9.2.0 can persist user-controlled Blob ContentType values and later use those values as the MIME type for client-side Blob objects. The shared generated openFile helper creates an object URL from the Blob and opens it in a new window. For...

msgpack5: Truncated map32 headers throw an unexpected error

Impact A truncated map32 header causes an out-of-bounds buffer read and throws RangeError instead of IncompleteBufferError. Applications that rely on IncompleteBufferError to wait for additional bytes may terminate a request, stream, or worker unexpectedly. No adjacent memory is disclosed because...

msgpack5: Many buffered values can exhaust the streaming decoder stack

Impact The streaming decoder recursively invokes itself for every complete value remaining in a chunk. A single chunk containing many small valid MessagePack values can exhaust the JavaScript call stack and interrupt the process or stream. Patches The streaming decoder now drains concatenated...

msgpack5: Reserved byte can cause unbounded stream buffering

Impact The reserved MessagePack byte 0xc1 is incorrectly treated as incomplete input. When it appears at the start of a decoder stream, all subsequent data is retained while the decoder waits for bytes that can never make the value valid, allowing memory exhaustion. Patches The decoder now reject...

msgpack5: Partial options disable prototype protection

Impact Passing an empty or partial options object disables the default protoAction: 'error' protection. A map containing a proto key can then replace the prototype of the decoded object, potentially changing inherited properties or causing unexpected behavior in downstream code. Only the decoded...

msgpack5: Deeply nested input can exhaust the decoder stack

Impact The decoder has no nesting-depth limit for arrays and maps. An attacker who can provide MessagePack input can use deeply nested containers to exhaust the JavaScript call stack and interrupt the process or request handler. Patches The decoder now limits nesting depth to 100 by default and...

msgpack5: Quadratic parsing in the streaming decoder

Impact The streaming decoder reparses an incomplete container from the beginning whenever another chunk arrives. A remote peer can split one valid MessagePack value across many small chunks, causing quadratic CPU usage and blocking the event loop. Patches The decoder now preserves incremental...

msgpack5: Decoding negative int64 values mutates the input buffer

Impact Decoding a negative signed 64-bit integer modifies the corresponding bytes in the caller-provided input buffer. Applications that retain or reuse encoded input for integrity checks, logging, or subsequent processing may observe silently corrupted data. Positive integers and other MessagePa...

PraisonAI: PGVector and Cassandra knowledge stores interpolate vector dimensions into DDL

PGVector and Cassandra knowledge stores interpolate vector dimensions into DDL Summary The PGVector and Cassandra knowledge-store backends validate SQL/CQL identifiers such as schema, keyspace, and collection names, but still insert the caller-controlled dimension argument directly into CREATE...

Pydantic AI Web chat UI (`Agent.to_web()`, `clai web`): the local chat endpoint does not validate the `Host` header

Summary The Pydantic AI development web chat UI Agent.toweb, clai web does not validate the Host header of incoming requests.

Excelize: Unbounded row number in Rows.Columns makes GetRows and the Rows iterator loop for days

Summary A worksheet whose number is far past Excel's 1,048,576-row limit makes File.GetRows and the Rows iterator loop once for every missing row. The row limit is checked in Rows.Next, but not in Rows.Columns, which also reads elements. A 1.5 KB file with after an ordinary first row keeps GetRow...

Excelize: Nil-pointer dereference in GetSlicers when a worksheet has extLst present but no drawing element

Summary GetSlicers guards only if ws.ExtLst == nil return slicer.go:816-818 and then immediately dereferences ws.Drawing.RID with no nil check on ws.Drawing itself. Drawing and ExtLst are two independently optional child elements of in xl/worksheets/sheetN.xml, populated separately by encoding/xm...

AsyncHttpClient CookieStore Silently Overrides Caller's Explicit Cookie Header via setHeader (Bypass of CVE-2024-53990 Fix)

Impact With the cookie store enabled, which is the default, a Cookie header that the caller sets on a request with setHeader or addHeader is thrown away whenever the store holds any cookie for the request's origin: the request's cookie list is written into that header afterwards and replaces it...

AsyncHttpClient: Cookies received over plaintext HTTP can plant, overwrite or delete Secure cookies set over HTTPS

Impact The cookie store ignores the scheme a Set-Cookie arrived on. draft-ietf-httpbis-rfc6265bis-22 approved to obsolete RFC 6265, in the RFC Editor queue Section 5.7 requires a user agent to ignore a cookie with the Secure attribute unless it arrived over a secure connection step 13, and to...

AsyncHttpClient: Unbounded WebSocket permessage-deflate decompression enables a decompression-bomb denial of service when compression is enabled

Impact With WebSocket compression enabled, the client inflates permessage-deflate messages with no limit on the decompressed size. It installed Netty's shared WebSocketClientCompressionHandler.INSTANCE, whose inflater is unbounded, and webSocketMaxFrameSize and webSocketMaxBufferSize only bound t...

AsyncHttpClient: Pooled connections can still be shared across NTLM, Negotiate and proxy logins

Impact The fix for GHSA-vvp4-63h8-v5pm in 3.0.13 folded the authenticated principal into the HTTP/1.1 connection pool key, so that a connection one principal authenticated with NTLM, Kerberos or SPNEGO is not handed to another. It left three cases out. In each, a socket that one identity...

Summary Pydantic AI's OpenTelemetry instrumentation supports InstrumentationSettingsincludecontent=False to exclude message content — user prompts, model completions, tool call arguments and responses, and any other message content — from exported telemetry, so that agents can be monitored withou...

Pydantic AI: SSRF cloud-metadata blocklist bypass via IPv6 zone identifiers

Summary When an application using Pydantic AI opts a URL into local network access — either a FileUrl with forcedownload='allow-local', or webfetchtoolallowlocalurls=True — the cloud-metadata blocklist could be bypassed by appending an IPv6 zone identifier to a metadata address for example...

PraisonAI: Plugin Auto-Discovery Executes Arbitrary Python Files Without Verification

Summary The plugin manager loads and executes arbitrary .py files from .praisonai/plugins/ directories both project-level and user home via importlib.util.specfromfilelocation + execmodule with zero code signing, integrity verification, or sandboxing. Any attacker who can write a file to the...

PraisonAI: CodeAgent Executes LLM-Generated Code Without Sandboxing and Leaks All Environment Secrets

Summary CodeAgent.executepython executes LLM-generated Python code in a subprocess with the complete parent-process environment os.environ.copy, zero AST validation, zero import restrictions, and no sandbox enforcement — even when CodeConfigsandbox=True is explicitly set. This allows an attacker...

PraisonAI: Human-in-the-loop tool approval is cached by tool name and silently reused for all subsequent calls with arbitrary arguments

Summary PraisonAI gates dangerous tools file writes, deletes, shell/code execution behind an interactive approval prompt. The first approval of a tool is cached for the remainder of the run and silently reused for all later invocations of that tool with arbitrary, unreviewed arguments. Root cause...

PraisonAI: DNS rebinding bypass in `web_crawl` SSRF protection allows internal response disclosure

Summary PraisonAI's webcrawl agent tool performs a server-side HTTP fetch of an agent/attacker-influenced URL. SSRF is meant to be prevented by issafecrawlurl, which resolves the hostname and rejects private/loopback/link-local IPs at validation time. The validated value is the URL string not a...

PraisonAI: Project config can auto-save agent output outside the project root

Project config can auto-save agent output outside the project root Summary praisonaiagents automatically reads project-local .praisonai/config.toml defaults when constructing an Agent. A repository-controlled config can set defaults.output.outputfile to an absolute path or a .. traversal path. Wh...

Excelize Decrypt: unrecoverable panics on malformed OLE/CFB encrypted workbooks

Summary Any file whose first 8 bytes are the OLE compound-file signature D0 CF 11 E0 A1 B1 1A E1 is routed by OpenFile/OpenReader/OpenBytes → openReaderAt → Decrypt. The version dispatch only guarantees lenEncryptionInfo = 4 before handing attacker-controlled EncryptionInfo/EncryptedPackage buffe...

Excelize: extractPart allocates attacker-controlled, unbounded and negative-sized buffers from CFB directory entries: remote panic / OOM DoS

Summary extractPart allocates directly from the mscfb directory-entry size with no clamping crypt.go:198, same missing bound at crypt.go:204: go buf := makebyte, entry.Size entry.Size is the raw streamSize field from the attacker-controlled CFB directory entry mscfb v1.0.8 fixFile, file.go:109-12...

Excelize ANCHORARRAY: mutually-referencing array formulas recurse unboundedly via re-entrant CalcCellValue, causing a fatal stack overflow

Summary ANCHORARRAY calc.go:15137 on current master evaluates each cell of the referenced spill range by calling the exported CalcCellValue, which unconditionally constructs a fresh calcContext — fresh entry marker, fresh iterations map, full MaxCalcIterations budget calc.go:896-900. The...

AsyncHttpClient: Digest authentication cnonce generated with a non-cryptographic random source

Impact The client nonce used in HTTP Digest authentication was generated from ThreadLocalRandom, a fast but non-cryptographic pseudorandom number generator. RFC 7616 section 3.3 requires the cnonce to be unpredictable, since it is part of what protects the Digest exchange against chosen-plaintext...

AsyncHttpClient: WebSocket proxy credentials sent to the origin server over a CONNECT tunnel

Impact When a ws:// request is routed through an HTTP proxy with proxy authentication configured, the client tunnels the connection with an HTTP CONNECT, the same as it does for https://. Once the tunnel is open, the WebSocket upgrade request that follows is sent through the tunnel directly to th...

AsyncHttpClient: Cookie Domain attribute is not checked against the public suffix list, so a cookie can be set for co.uk

Impact The cookie store decides whether a Domain attribute may be accepted using only the domain-matching rule of RFC 6265 Section 5.1.3, which asks whether the request host is the domain or ends with a dot followed by it. Section 5.3 step 5, which additionally requires rejecting a Domain that is...

AsyncHttpClient: Replay to a different host sends the original host request and credentials to the new host

Impact When a request is replayed onto a different host, the client updates only the current request and leaves the target request pointing at the original host. Four consumers read that stale value, and each one sends the first host's request, credentials, or both to the second host. A replay...
