Summary
A vulnerability in SitemapLoader.parse_sitemap in langchain_community/document_loaders/sitemap.py allows an attacker who controls a sitemap to point a nested sitemap entry at an internal address, even when restrict_to_same_domain is set to True. The server will fetch internal content and disclose it in returned documents.
Risk Assessment
An attacker could access internal network resources and disclose their content, potentially leading to leakage of sensitive information.
Recommendation
Apply vendor patch or strengthen domain and IP validation in SitemapLoader to block access to private, loopback, and link-local addresses.

- CVE-2026-9055Critical
The Booking for Appointments and Events Calendar – Amelia (Premium) plugin for WordPress versions 8.0 - 9.6.2 is vulnerable to privilege escalation due to insufficient validation of the 'type' parameter in the customer update endpoint. This allows customers to set their role to 'manager' and trigger creation of a WordPress user with the wpamelia-manager role when 'externalId' is set to 0. Unauthenticated attackers can escalate to administrator by first elevating to manager, then creating a provider entity linked to an administrator user ID and overwriting that administrator's password.

Team Password Manager before version 14.184.308 fails to enforce authentication requirements in the local account password reset flow. Unauthenticated attackers can reset local account passwords and authenticate as those users to gain unauthorized access.
- CVE-2026-84480Critical
WWBN AVideo fails to validate password recovery token expiration in userRecoverPassSave.json.php, allowing attackers to use expired tokens to reset account passwords indefinitely. Attackers who obtain a recovery token can use it at any time to change the target account's password and gain full account access.
- CVE-2026-84479Critical
WWBN AVideo (current e01e41ecc and earlier) makes three login-time security controls depend solely on the client-supplied User-Agent header. The isAVideoEncoder()/isAVideoMobileApp() checks match HTTP_USER_AGENT against a hardcoded literal ("AVideoEncoder"/"AVideoMobileApp") with no IP check or shared secret. An attacker who submits valid credentials and sets User-Agent: AVideoEncoder bypasses two-factor authentication, skips brute-force captcha escalation, and avoids being recorded in the login/device audit history. No patch is available at the time of publication.
- CVE-2026-84372Critical
Predis, a Redis and Valkey client for PHP, versions 3.0.0-RC1 through 3.3.0, improperly processes the RESP buffer in aggregate connections, allowing an attacker to inject additional commands via keys or values containing CRLF sequences. This can lead to shard-wide cache deletion, targeted data modification, data reads, or node disruption. Only pipeline() is affected; transactions are not vulnerable. Fixed in version 3.3.0.
- CVE-2026-75604Critical
Next.js, a React framework for full-stack applications, versions 13.4.0 through 15.5.24 and 16.3.3, on Windows-hosted servers does not properly escape backslashes in route segments when constructing cache paths, allowing a remote attacker to traverse outside the cache root and expose private data, including the server-reference-manifest encryption key. Disclosure of this key can enable remote code execution. Fixed in versions 15.5.24 and 16.3.3.
- CVE-2023-54391Critical
Proxmox Virtual Environment (VE) versions 7.0 through 8.0 contain an authentication bypass vulnerability in libpve-access-control before 8.0.4, allowing unauthenticated attackers to authenticate as any existing enabled user without a configured second factor by supplying an arbitrary tfa-challenge value in the API login endpoint. Attackers can completely skip password verification, gaining unauthorized access including to the root@pam account. All affected releases are end of life.
- CVE-2026-73749Critical
Multiple vulnerabilities exist in a daemon of AOS-CX that may allow for improper processing of malformed input. An unauthenticated remote attacker could exploit these vulnerabilities by sending specially crafted packets to the affected service. Successful exploitation could result in remote code execution with elevated privileges.
- CVE-2026-76658Critical
A vulnerability has been identified in the SSH daemon of HPE Networking Fabric Composer that could allow an unauthenticated remote attacker to gain administrative access to vulnerable AFC hosts. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system leading to complete system compromise.
- CVE-2026-76657Critical
Vulnerabilities have been identified in the API of HPE Networking Fabric Composer that could potentially allow an unauthenticated remote attacker to circumvent existing authentication controls. Successful exploitation could allow an attacker to gain administrative privileges leading to complete compromise of the HPE Networking Fabric Composer host.
Original NVD description (English source)
SitemapLoader.parse_sitemap in langchain_community/document_loaders/sitemap.py applies the documented restrict_to_same_domain control only to leaf url entries. The loop over url elements filters cross-domain locations, but the loop over nested sitemap elements passes the child loc straight to self.scrape_all([loc.text], "xml"), which reaches WebBaseLoader.scrape_all and an aiohttp GET, with no domain comparison and no check for private, loopback or link-local destinations. An attacker who controls or influences an ingested sitemap can therefore point a nested sitemap entry at an internal address and make the server fetch it even when the deploying application set restrict_to_same_domain to True specifically to confine outbound requests. The fetched content is parsed and surfaces in the returned Documents, so internal responses are disclosed to the caller rather than merely requested.
