Title
eosphoros-ai DB-GPT Jinja2 Template __init__.py FileBasedSkill.get_prompt special elements in template engine
Summary
A security vulnerability has been detected in eosphoros-ai DB-GPT up to 0.8.1. The affected element is the function FileBasedSkill.get_prompt of the file packages/dbgpt-core/src/dbgpt/agent/skill/claude_skill/__init__.py of the component Jinja2 Template Handler. The manipulation leads to improper neutralization of special elements used in a template engine. The attack may be initiated remotely. The exploit has been disclosed publicly and may be used. Upgrading to version 0.8.2 is sufficient to fix this issue. The identifier of the patch is a9e7a3c026d114fcfb4ffe3eaf78851a636ded16. It is suggested to upgrade the affected component.

Title
svg-sanitizer 0.5.0 before 1.1.0 Incomplete url() Filtering in SVG Attributes
Summary
svg-sanitizer from 0.5.0 before 1.1.0 contains an incomplete filtering vulnerability that allows attackers to bypass remote URL removal by using CSS escape sequences inside url() in SVG presentation attributes. Attackers can supply SVG files with attributes like fill containing escaped slashes that browsers resolve to remote URLs, triggering external requests and enabling data exfiltration.

CVE-2026-48208 (GCVE-0-2026-48208)

Vulnerability from cvelistv5 – Published: 2026-06-01 03:32 – Updated: 2026-06-01 13:19
VLAI
Title
Denial-of-Service via SVG Rendering in Ticket
Summary
An improper neutralization of active SVG content in OTRS or ((OTRS)) Community Edition ticket article rendering allows attackers to inject specially crafted SVG payloads via email content, leading to browser-side resource exhaustion and denial of service when affected tickets are opened by an agent or customer. The issue can be exploited without JavaScript execution and is not mitigated by the configured Content Security Policy (CSP). This issue affects OTRS: * 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.4.X Please note that ((OTRS)) Community Edition 6.x and before are vulnerable. Products based on the ((OTRS)) Community Edition also very likely to be affected
