OpenClaw < 2026.3.24 - Denial of Service via Feishu Webhook Pre-Auth Body Parsing
Summary
OpenClaw before 2026.3.24 contains an incomplete fix for CVE-2026-32011 where the Feishu webhook handler accepts request bodies with permissive limits of 1MB and 30-second timeout before signature verification. An unauthenticated attacker can exhaust server connection resources by sending concurrent slow HTTP POST requests to the Feishu webhook endpoint, blocking legitimate webhook deliveries.

Title
Denial of service (DOS) vulnerability in SAP BusinessObjects Business Intelligence Platform (AdminTools)
Summary
SAP BusinessObjects Business Intelligence Platform (AdminTools) allows an authenticated attacker with user privileges to execute a specific query in AdminTools that could cause the Content Management Server (CMS) to crash, rendering the CMS partially or completely unavailable and resulting in the denial of service of the Content Management Server (CMS). Successful exploitation impacts system availability, while confidentiality and integrity remain unaffected.

Title
devalue vulnerable to denial of service due to memory/CPU exhaustion in devalue.parse
Summary
Svelte devalue is a JavaScript library that serializes values into strings when JSON.stringify isn't sufficient for the job. From 5.1.0 to 5.6.1, certain inputs can cause devalue.parse to consume excessive CPU time and/or memory, potentially leading to denial of service in systems that parse input from untrusted sources. This affects applications using devalue.parse on externally-supplied data. The root cause is the ArrayBuffer hydration expecting base64 encoded strings as input, but not checking the assumption before decoding the input. This vulnerability is fixed in 5.6.2.
Severity
7.5 (High)

Title
devalue vulnerable to denial of service due to memory exhaustion in devalue.parse
Summary
Svelte devalue is a JavaScript library that serializes values into strings when JSON.stringify isn't sufficient for the job. From 5.3.0 to 5.6.1, certain inputs can cause devalue.parse to consume excessive CPU time and/or memory, potentially leading to denial of service in systems that parse input from untrusted sources. This affects applications using devalue.parse on externally-supplied data. The root cause is the typed array hydration expecting an ArrayBuffer as input, but not checking the assumption before creating the typed array. This vulnerability is fixed in 5.6.2.

Title
Text::LineFold versions through 2019.001 for Perl duplicate the output based on the number of special break characters
Summary
Text::LineFold versions through 2019.001 for Perl duplicate the output based on the number of special break characters.
Text::LineFold splits the input string by specific line break characters (such as VT, FF and others) into segments, but applies the break function to the entire string, not just the segment.
A side effect of this is that the full input can be duplicated for each segment. Besides being incorrect, this can lead to unexpected resource consumption and possible denial of service.
Note that Text::LineFold is part of the Unicode-LineBreak distribution, which may have a higher version number than the module.

Title
Denial of service (DOS) vulnerability in SAP BusinessObjects BI Platform
Summary
SAP BusinessObjects BI Platform allows an unauthenticated attacker to send specially crafted requests that could cause the Content Management Server (CMS) to crash and automatically restart. By repeatedly submitting these requests, the attacker could induce a persistent service disruption, rendering the CMS completely unavailable. Successful exploitation results in a high impact on availability, while confidentiality and integrity remain unaffected.

Mitigation
Architecture and Design
An application must make resources available to a client commensurate with the client's access level.
Mitigation
Architecture and Design
An application must, at all times, keep track of allocated resources and meter their usage appropriately.
Mitigation
System Configuration
Consider disabling resource-intensive algorithms on the server side, such as Diffie-Hellman key exchange.
