Title
Vyper through 0.5.0b1 Literal Value Manipulation via Line Separators
Summary
Vyper 0.1.0b1 before 0.1.0b17 and 0.4.1 through 0.5.0b1 builds its source-line table with str.splitlines(), which treats characters like form feed and U+2028 as line breaks the Python parser ignores, so numeric literals are classified and validated from shifted source text. An attacker contributing source code can hide these characters in comments, strings or indentation to silently change address, integer or decimal constants.

Title
adm-zip before 0.6.1 Duplicate ZIP Entry Name Validation Bypass
Summary
adm-zip before 0.6.1 contains an inconsistent entry resolution vulnerability that allows attackers to bypass content validation by supplying ZIP archives with duplicate entry names. Attackers can craft archives where getEntry() returns the last duplicate while extractAllTo() writes the first, causing unvalidated bytes to be written to disk.

Title
@fastify/middie vulnerable to path-scoped middleware bypass via scope prefix mismatch
Summary
@fastify/middie is the Express-style middleware engine for Fastify. In versions from 9.0.0 through 9.3.5, the use() function joined a path-scoped middleware's mount path to the plugin scope prefix in a way that could diverge from the path Fastify's router serves, most often when the scope prefix ended in a slash, and also for array mount paths and for mount paths written without a leading slash. When the two paths disagreed, the middleware was silently skipped while the route handler still ran, so path-scoped middleware such as authentication, authorization, or rate limiting could be bypassed by a single unauthenticated request. The issue is fixed in @fastify/middie 9.3.6, and users should upgrade to 9.3.6 or later. As a workaround, enforce authorization in a Fastify hook such as preHandler that runs after the router has resolved the request.

Title
@fastify/express vulnerable to path-scoped middleware bypass via absolute-form request targets
Summary
@fastify/express is a Fastify plugin that runs Express middleware inside Fastify. In versions 4.0.5 through 4.0.8, when Fastify runs with the non-default ignoreDuplicateSlashes option enabled, the plugin matches path-scoped Express middleware against a URL whose duplicate-slash normalization has also collapsed the separator after an absolute-form request target's scheme, so Fastify's router resolves the request to the scoped path and runs the handler while the Express layer no longer sees that path. As a result, a request using an absolute-form target can reach a handler on a scoped route such as an admin path while the middleware for authentication, authorization, or rate limiting is skipped. An unauthenticated attacker needs only the non-default ignoreDuplicateSlashes option to be enabled. The issue is fixed in @fastify/express 4.0.9, and users should upgrade to 4.0.9 or later. As a workaround, enforce authentication in a Fastify hook such as preHandler that runs after the router resolves the request, or leave ignoreDuplicateSlashes at its default.

Title
Cpanel::JSON::XS versions from 4.42 before 4.80 for Perl let input chunking change the decoded value of top-level numbers in incr_parse
Summary
Cpanel::JSON::XS versions from 4.42 before 4.80 for Perl let input chunking change the decoded value of top-level numbers in incr_parse.
allow_nonref is enabled by default and incr_parse inherits it. A top-level number, true, false or null has no closing delimiter, so the incremental parser decodes whatever has arrived. The bytes 12 decode as one value when read together, but as 1 and then 2 when split across two reads.
A peer that can influence read boundaries can change how many messages a stream consumer decodes and what values they carry.

Title
Roo-Code through 3.54.0 Auto-Approve Bypass via Command Substitution at Command Position
Summary
Roo Code through 3.54.0 contains a command approval bypass vulnerability in parseCommandLine() that allows attackers to auto-approve arbitrary shell commands by placing a command substitution in command position. Attackers using indirect prompt injection can submit commands like $(echo touch /tmp/x) that pass the echo allowlist check, causing the shell to execute the output without user approval.

Title
Roo-Code through 3.54.0 Auto-Approve Bypass via Quote Masking Desynchronization
Summary
Roo Code through 3.54.0 contains a command approval bypass vulnerability that allows attackers to auto-approve denied shell commands by abusing quote-masking regex in parseCommandLine(). Attackers can use indirect prompt injection with escaped or single-quoted double quotes to hide command separators behind allowlisted prefixes like echo, executing commands without user approval.

Title
Roo-Code through 3.54.0 Auto-Approve Bypass via Redirect Operator Stripping
Summary
Roo Code through 3.54.0 contains a command approval bypass vulnerability in getCommandDecision() that allows attackers to auto-approve denied shell commands by prefixing them with a bare >& redirect. Attackers using indirect prompt injection can make the allowlist match a redirect target like echo while the shell runs the denied command on the developer machine.

Title
fast-uri vulnerable to host confusion via unchecked WHATWG host canonicalization
Summary
fast-uri is a dependency-free RFC 3986 URI parser and serializer for Node.js. In versions from 2.4.2 through 2.4.7, from 3.1.3 through 3.1.8, and from 4.0.1 through 4.2.2, for HTTP-family schemes the canonicalizeHost() function passes the parsed host to the WHATWG URL parser and adopts its hostname without checking that the parser consumed the entire input as a host, so the authority can be silently rewritten: data before an at-sign is dropped and tab, carriage-return, and line-feed characters are stripped, with no error reported. An application that enforces host-based policy such as denylists, loopback filtering, redirect validation, or outbound proxy routing on one representation can then see the canonical host diverge from what it checked, allowing traffic to be steered to an unintended destination. The issue is fixed in fast-uri 2.4.8, 3.1.9, and 4.2.3, and users should upgrade to one of these versions or later. As a workaround, reject an authority that contains more than one at-sign or any tab, carriage-return, or line-feed before calling fast-uri, or treat any non-empty parse error as fatal and compare hosts only from the same parse result.

CAPEC-105: HTTP Request Splitting
An adversary abuses the flexibility and discrepancies in the parsing and interpretation of HTTP Request messages by different intermediary HTTP agents (e.g., load balancer, reverse proxy, web caching proxies, application firewalls, etc.) to split a single HTTP request into multiple unauthorized and malicious HTTP requests to a back-end HTTP agent (e.g., web server).
