PYSEC-2026-397 llama-index-core Prompt Injection vulnerability leading to Arbitrary Code Execution

A vulnerability was identified in the executils class of the llamaindex package, specifically within the safeeval function, allowing for prompt injection leading to arbitrary code execution. This issue arises due to insufficient validation of input, which can be exploited to bypass method...

PYSEC-2026-396 llama-index-core Command Injection vulnerability

A command injection vulnerability exists in the run-llama/llamaindex repository, specifically within the safeeval function. Attackers can bypass the intended security mechanism, which checks for the presence of underscores in code generated by LLM, to execute arbitrary code. This is achieved by...

PYSEC-2026-398 llama-index-packs-finchat SQL Injection vulnerability

A vulnerability in the FinanceChatLlamaPack of the llama-index-packs-finchat package, versions up to v0.3.0, allows for SQL injection in the runsqlquery function of the databaseagent. This vulnerability can be exploited by an attacker to inject arbitrary SQL queries, leading to remote code...
