Title
Chartbrew: AI orchestrator run_query SQL blocklist bypass enables arbitrary file read on connected PostgreSQL (quoted-identifier + pg_stat_file/pg_ls_* sibling gap)
Summary
Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. In 5.2.2, the AI SQL blocklist omitted sibling PostgreSQL filesystem functions and failed to match double-quoted identifier forms of denied functions. The vulnerable surface is the AI query tool's PostgreSQL SQL-validation blocklist. A team Owner or Admin uses an AI-enabled PostgreSQL connection whose database role can call server-side file functions and causes generated SQL to use an unlisted sibling function or a double-quoted denied function. Unlisted sibling functions remain allowed, and double-quoted function identifiers bypass the denylist regular expressions and reach PostgreSQL. AI features must be enabled and the user must have elevated Chartbrew privileges. A PostgreSQL superuser or pg_read_server_files role can resolve absolute paths to files readable by the PostgreSQL OS user, while a non-superuser is limited to the source-stated PGDATA-relative scope. This vulnerability is fixed in 5.2.3.

Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
