### Summary An attacker can send a `/api/v1/files/upload/` request without any authentication token/cookies and abuse a very long multipart form boundary to make the langflow app unusable for all users for an indefinite amount of time. ### Details https://github.com/langflow-ai/langflow/blob/v1.0.18/src/backend/base/langflow/api/v1/files.py#L40 The file upload function will try to process the multipart form data even if it is malformed and contains a payload such as an extremely large amount
### Impact The `HmacSha256` class contained two functions: - `hash(payload)` — a plain unkeyed SHA-256 digest. The `Hmac` prefix in the class name was misleading; this function has no key parameter, so it could never have been an HMAC. - `hmacSHA256(key, data)` — a properly keyed HMAC-SHA256. A reader who didn't engage with the function signature could in principle have assumed `HmacSha256.hash(payload)` was somehow keyed, but the absence of any key parameter made that misuse unlikely in pract
### Summary vcrpy deserializes YAML cassette files with PyYAML's object-constructing loader (`yaml.CLoader` / `yaml.Loader`) instead of the safe loader (`yaml.CSafeLoader` / `yaml.SafeLoader`). A cassette containing a `!!python/object/apply:` (or similar) tag therefore executes arbitrary Python code the moment the cassette is loaded — including through the normal `VCR().use_cassette()` path, before any HTTP interaction is replayed. This is **not** limited to environments lacking the libYAML C
## XML Entity Expansion (Billion Laughs) DoS in XMLSitemapParser ### Summary `ultimate-sitemap-parser` version 1.8.0 and earlier parse attacker-controlled XML content using Python's `xml.parsers.expat` without any restriction on DTD declarations or recursive entity references. An attacker who can serve a malicious sitemap can trigger exponential XML entity expansion (the "Billion Laughs" attack), causing unbounded CPU and memory consumption in the victim process. No authentication, user intera
## Gzip Decompression Bomb Bypasses Sitemap Size Limit ### Summary `ultimate-sitemap-parser` enforces a 100 MiB size limit on sitemap responses, but applies it only to the **compressed** bytes received over the network. When a `.gz` sitemap is fetched, `usp/helpers.py:239` calls `gzip_lib.decompress(data)` with no output-size cap, allowing an attacker-controlled server to serve a small gzip-compressed payload (~549 KB) that expands to over 120 MiB in process memory. This completely bypasses th
### Summary The user supplied class value is fed directly into the sprintf call that creates HTML. You can add a quote to escape the class and then inject arbitrary html/javascript to the final output. ### Details The template [here](https://github.com/StarCitizenWiki/mediawiki-extensions-EmbedVideo/blob/a573a16d925ee0ea0d34b360856dc8ab0b88f822/includes/EmbedService/EmbedHtmlFormatter.php#L138) adds a figure with a class that is substituted in. This value is provided to sprintf [here](https://g
### Summary When passing an unknown service name to embedvideo, an error message is rendered containing the invalid service name. The service name is not sanitized and can contain HTML. ### Details There is a hardcoded list of allowed services in a switch statement inside `EmbedServiceFactory#newFromName` [here](https://github.com/StarCitizenWiki/mediawiki-extensions-EmbedVideo/blob/a573a16d925ee0ea0d34b360856dc8ab0b88f822/includes/EmbedService/EmbedServiceFactory.php#L105). When the service na
### Summary `convert()` builds the nested tree by using each flat record's `id` and `parent` field values directly as object keys, with no guard against `__proto__` / `constructor` / `prototype`. A record whose `parent` is the string `"__proto__"` makes `temp[parent]` resolve to `Object.prototype`, and the following `initPush(...)` writes attacker-controlled data onto the global prototype. Any application that passes attacker-influenced records to `convert()` is affected, and the base prototyp
## Summary Blocky accepts and caches forged DNS answers while `dnssec.validate: true` is enabled. The issue has two related exploit paths: 1. **Basic DNSSEC validation bypass.** If an untrusted upstream returns an unsigned positive answer for a DNSSEC-signed public domain, Blocky classifies the response as `Insecure` solely because the response contains no RRSIG records. It does not first check the DS/DNSKEY chain to determine whether the queried name is below a signed delegation. The forged u
Kozou compiles a PostgreSQL schema into an Admin UI, a REST API, and an MCP server. Several hardening gaps in the bundled HTTP surfaces and the scaffolded dev stack are fixed in **1.8.1**. ## Issues 1. **MCP HTTP server lacked DNS-rebinding protection.** The Streamable HTTP transport is unauthenticated and loopback by default. Without `Host`/`Origin` validation, a malicious web page in the operator's browser could rebind a hostname it controls to the loopback address and drive the MCP endpoint
The Database for Contact Form 7, WPforms, Elementor forms plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the view_page function in all versions up to, and including, 1.5.1. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Successful exploitation requires an administrator to view or edit the p
Capgo before 12.128.2 contains a scope escalation vulnerability in the POST /functions/v1/apikey endpoint that allows app-limited API keys to mint unrestricted keys by setting empty limits. Attackers with a compromised app-limited key can create an unrestricted key with org-wide access to resources like app listings and other protected endpoints.
Capgo before 12.128.12 allows authenticated users to modify their mutable public.users.email to arbitrary addresses, which the SSO provisioning endpoint trusts as an account-merge key. Attackers can pre-position their account with a victim's corporate SSO email, causing the provision-user endpoint to merge the victim's SSO identity into the attacker-controlled account.
Capgo before 12.128.2 contains an information disclosure vulnerability in Supabase PostgREST RPC endpoints is_trial_org and is_paying_org that allows unauthenticated attackers to enumerate organizations and disclose billing status using the public sb_publishable key. Attackers can invoke these endpoints to determine organization existence via distinguishable return values and identify paying customers for targeted profiling.
### Summary The Konnected integration registers an HTTP endpoint, `KonnectedView` (`homeassistant/components/konnected/__init__.py`), that is marked as **not requiring authentication** (`requires_auth = False`). A comment next to that line says auth is instead handled "via the access token from configuration." That promise is only half true: - **Write requests (POST and PUT)** are handled by `update_sensor()`, which *does* check the request's `Authorization: Bearer <token>` header against the
### Summary There exists an **arbitrary file write vulnerability** in `py7zr` (1.1.0, latest), which allows symbolic links to be recreated outside the destination directory via crafted malicious symbolic link chains. When using `extractall` to extract an archive, the library restores these symbolic links, linking them to arbitrary directories on the host file system. Subsequent extraction of regular files through these symbolic links can result in arbitrary file writes. This vulnerability may le
### Impact The default `security.http.urls` policy denies requests to loopback, internal, and cloud-metadata IPv4 literals (e.g. `http://127.0.0.1/`, `http://169.254.169.254/`). The deny rule only matched dotted-decimal notation, so alternate IPv4 encodings of the same addresses — integer, hex, or octal, which contain no dot — passed the policy: - `http://2130706433/` → `127.0.0.1` - `http://2852039166/` → `169.254.169.254` (cloud metadata) - `http://0x7f000001/`, `http://01770
# Unauthenticated nested page API leaks restricted & unpublished content - **Location:** `app/controllers/alchemy/api/pages_controller.rb:28` (`Api::PagesController#nested`) - **Affected version:** Alchemy CMS 8.3.0.dev (Rails 8.1.3) ## Description The unauthenticated `GET /api/pages/nested` endpoint returns the full page tree to any anonymous caller, including restricted (member-only) pages and unpublished/draft pages that should be hidden. Appending `?elements=true` additionally dumps the e
Capgo (Cap-go/capgo) before 12.128.2 contains an improper access control vulnerability in the SECURITY DEFINER PostgREST RPC function public.record_build_time, which is granted to the anon role and callable with only the public Supabase publishable (sb_publishable_*) anon key. An unauthenticated attacker can insert rows into public.build_logs for arbitrary organizations and, because the function uses ON CONFLICT (build_id, org_id) DO UPDATE, can overwrite existing usage/billing records by reusin
### Impact Possible data exposure. #### Summary While downloading packages from a maliciously crafted URL, some git operations against that URL could allow arbitrary file read. This might allow disclosure of confidential information. #### Details OpenTofu relies on [go-getter](https://github.com/hashicorp/go-getter) for downloading packages like providers and modules. While doing so from a maliciously crafted URL, the operator could be affected by confidential information disclosure. The go-g
