What This Means For Your System

Each point below is derived directly from this CVE's CVSS v3.1 vector — not editorial opinion.

1

Exploitable remotely over the internet — no physical or local access needed.

2

No special preconditions — the attack is reliably repeatable.

3

No authentication required — unauthenticated attackers can exploit directly.

4

A victim must take a specific action (open file, click link) for exploitation.

5

Successful exploitation causes: partial information disclosure, limited data modification, potentially cascading beyond the vulnerable component.

CVE-2016-20054MEDIUM

Nodcms contains a cross-site request forgery vulnerability that allows attackers to perform unauthorized administrative actions by crafting malicious forms. Attackers can trick authenticated administrators into submitting requests to admin/user_manipulate and admin/settings/generall endpoints to create users or modify application settings without explicit consent.

CVE-2026-5527MEDIUM

A weakness has been identified in Tenda 4G03 Pro 1.0/1.0re/01.bin/04.03.01.53. Affected by this issue is some unknown functionality of the file /etc/www/pem/server.key of the component ECDSA P-256 Private Key Handler. This manipulation causes use of hard-coded cryptographic key . It is possible to initiate the attack remotely.

CVE-2026-5528MEDIUM

A security vulnerability has been detected in MoussaabBadla code-screenshot-mcp up to 0.1.0. This affects an unknown part of the component HTTP Interface. Such manipulation leads to os command injection. It is possible to launch the attack remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

CVE-2026-5529MEDIUM

A vulnerability was detected in Dromara lamp-cloud up to 5.8.1. This vulnerability affects the function pageUser of the file /defUser/pageUser of the component DefUserController. Performing a manipulation results in improper authorization. The attack can be initiated remotely. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.

CVE-2018-25246HIGH

Wikipedia 12.0 contains a denial of service vulnerability that allows unauthenticated attackers to crash the application by submitting oversized input through the search functionality. Attackers can paste a large buffer of repeated characters into the search bar to trigger an application crash.

CVE-2026-31842HIGH

Tinyproxy through 1.11.3 is vulnerable to HTTP request parsing desynchronization due to a case-sensitive comparison of the Transfer-Encoding header in src/reqs.c. The is_chunked_transfer() function uses strcmp() to compare the header value against "chunked", even though RFC 7230 specifies that transfer-coding names are case-insensitive. By sending a request with Transfer-Encoding: Chunked, an unauthenticated remote attacker can cause Tinyproxy to misinterpret the request as having no body. In this state, Tinyproxy sets content_length.client to -1, skips pull_client_data_chunked(), forwards request headers upstream, and transitions into relay_connection() raw TCP forwarding while unread body data remains buffered. This leads to inconsistent request state between Tinyproxy and backend servers. RFC-compliant backends (e.g., Node.js, Nginx) will continue waiting for chunked body data, causing connections to hang indefinitely. This behavior enables application-level denial of service through backend worker exhaustion. Additionally, in deployments where Tinyproxy is used for request-body inspection, filtering, or security enforcement, the unread body may be forwarded without proper inspection, resulting in potential security control bypass.

CVE-2026-5526HIGH

A security flaw has been discovered in Tenda 4G03 Pro up to 1.0/1.1/04.03.01.53/192.168.0.1. Affected by this vulnerability is an unknown functionality of the file /bin/httpd. The manipulation results in improper access controls. The attack may be performed from remote. The exploit has been released to the public and may be used for attacks.
