Lifecycle Timeline
3DescriptionCVE.org
PraisonAI before 1.5.115 contains an information disclosure vulnerability in the MultiAgentLedger component that allows attackers to access sensitive data by registering agents with duplicate IDs. Attackers can exploit the lack of agent ID uniqueness enforcement to share ledger instances and expose system prompts and conversation history between agents.
AnalysisAI
Information disclosure in PraisonAI before 1.5.115 allows authenticated agents to read other agents' system prompts and conversation history by exploiting missing uniqueness enforcement on agent identifiers in the MultiAgentLedger component. An attacker who can register an agent with a colliding ID receives the same ledger instance as the victim, breaking tenant isolation in multi-agent deployments. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be able to authenticate to the PraisonAI application and invoke MultiAgentLedger.get_agent_ledger with a chosen agent ID (PR:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N, 7.1 High) is internally consistent with the description: network reachable, low complexity, requires the attacker to be an authenticated agent registrant (PR:L), no user interaction, and high confidentiality impact with no integrity or availability effect. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | In a multi-tenant PraisonAI deployment, an attacker authenticates as a low-privileged user and registers an agent using a known or guessed ID matching a victim agent (e.g., 'user1_agent'). MultiAgentLedger returns the existing ledger object, and the attacker calls its read methods to extract the victim's tracked system prompts and conversation history. … |
| Remediation | Vendor-released patch: 1.5.115 - upgrade praisonaiagents to 1.5.115 or later via pip install --upgrade praisonaiagents, per the GHSA-766v-q9x3-g744 advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
