Inline comments:
In `@server/src/markdownify/markdown.ts`:
- Line 80: After calling unwrapRedirect() at line 80 and in the SafeLinks/Google
handling sections around lines 214-221, validate that the resulting href URL has
a safe scheme before using it in Markdown output. Add a check to ensure the
unwrapped URL starts with a safe scheme like http:// or https://, and reject or
sanitize URLs with dangerous schemes like javascript:, data:, or other unsafe
protocols. This validation must occur after unwrapping but before the href is
written into the Markdown link output to prevent security bypass where
originally safe URLs could become malicious after unwrapping.
- Around line 249-255: The CHROME_LANDMARK_SELECTOR is being removed globally
without checking if it's within primary content areas, which can delete
legitimate sidebars and metadata. Apply the same guard condition used for header
and footer elements to CHROME_LANDMARK_SELECTOR removal. Instead of directly
removing all CHROME_LANDMARK_SELECTOR matches, iterate through them and only
remove those that are not parents of article, main, or section elements, using
the same pattern as the header/footer conditional block.
In `@server/src/markdownify/scrape.ts`:
- Around line 44-76: The closeButton detection logic scans the entire document
globally for buttons matching CLOSE_LABELS without verifying they are actually
inside modal/overlay/dialog containers, which can accidentally click legitimate
page controls. Refactor the code to first identify actual modal or overlay
containers (using selectors like [role="dialog"], [role="alertdialog"], elements
with class*="modal", etc.), then only search for and click close buttons that
are descendants of those identified containers. This ensures the code only
closes actual overlays rather than clicking arbitrary buttons that happen to
have labels like "Close", "Got it", or similar text.
In `@server/src/routes/storage.ts`:
- Around line 1683-1711: The stuck detection logic in the database query
starting with Op.and is incorrectly flagging browserless document
extraction/parse runs as stuck because they have no active browser session by
design. Modify the query condition to exclude document jobs from this stuck
detection check, either by adding a filter condition to the Op.and clause to
exclude document-type runs, or by checking the run type before processing it in
the loop and skipping document jobs that legitimately run without a browser
session. This ensures that runs without browsers are only treated as stuck if
they are actual browser-based runs.
- Around line 1685-1691: The watchdog query assumes startedAt values are in US
locale format (FMMM/FMDD/YYYY, FMHH12:MI:SS AM), but startedAt is actually
stored using toLocaleString() which produces different formats depending on user
locale (German: 15.6.2024, French: 15/06/2024, etc.). When PostgreSQL encounters
a non-matching format, to_timestamp() fails and the entire watchdog query
breaks, preventing recovery of stuck runs. Store startedAt as an ISO 8601
timestamp or use the database's native timestamp type instead of
locale-formatted strings, and update the watchdog query logic to compare the
timestamp directly with a cutoff date (now() minus
STUCK_RUNNING_THRESHOLD_MINUTES) instead of attempting to parse variable locale
formats.
In `@server/src/sdk/browserAgent.ts`:
- Around line 675-678: The actionSignatureCounts counter tracks repeated actions
globally without considering page changes, causing valid sequences like clicking
the same "Next" button across multiple pages to fail. Modify the logic around
actionSignatureCounts and MAX_REPEATS_PER_ACTION to track the page state before
incrementing the repetition counter, and reset or bypass the counter when the
page has changed since the last action. Only flag an action as stuck (update
stuckSignature) if the same signature is repeated on the same page without
progress, rather than just counting total occurrences globally.
- Around line 488-497: The current implementation of getRegistrableDomain uses a
naive label-slicing approach that fails for multi-label public suffixes (e.g.,
.co.uk), creating a security vulnerability where unrelated sites like
shop.example.co.uk and login.attacker.co.uk could be treated identically.
Replace this implementation with a public-suffix-aware parser library such as
tldts or psl that properly extracts the registrable domain while handling
multi-label public suffixes correctly. For IP addresses, implement exact-host
matching as a fallback since they don't have traditional domain structure. The
function is used at two critical points to validate navigation (at line 533 for
validating navigation action URLs and at line 670 for initializing the allowed
domain), so the fix must correctly handle all domain formats to prevent
navigation to attacker-controlled sites.
In `@server/src/sdk/selectorValidator.ts`:
- Around line 479-515: The evalXPath call on the line evaluating listSelector
assumes it is always an XPath expression, but listSelector can be a CSS
selector. Detect whether listSelector is a CSS or XPath selector using the same
pattern already applied to field.selector (checking if it starts with '//' or
'(//'), then use the appropriate evaluator for that selector type. This ensures
CSS list selectors are properly evaluated instead of returning an empty object,
and when the list selector matches nothing, ensure the code returns zero rates
for all fields instead of allowing undefined rates to propagate downstream.
In `@server/src/task-runner.ts`:
- Around line 328-331: The promptResult object shape is inconsistent between the
try and catch blocks in the smart-query handler. The successful case on line 328
includes a success field with agentResult.success, but the catch block on line
331 creates a promptResult object without the success field. Add success: false
to the object being assigned in the catch block's
serializableOutput.promptResult assignment to maintain consistent object shape
and allow consumers to reliably detect failures.

Avoid removing in-content landmarks globally.

Scope close-button clicks to actual overlays.

Exclude browserless document jobs from browser-pool stuck detection.
Document extraction/parse runs are created as running with no real browser session by design, so this watchdog will re-queue or fail any document job that legitimately runs longer than 16 minutes. Filter them out or use a separate heartbeat/job-state signal before treating “no browser” as stuck.
Proposed guard

PostgreSQL to_timestamp function behavior when format doesn't match
💡 Result:
The PostgreSQL to_timestamp function behaves in a strict manner when the input string does not match the provided format template, typically resulting in an error [1][2]. Key aspects of its behavior include: 1. Error Handling: When the input string does not align with the format mask, PostgreSQL generally raises an error with SQLSTATE 22007 (invalid_datetime_format) [2]. This error indicates that the provided string is syntactically or semantically invalid for the target timestamp type [2]. 2. Strictness and Exceptions: While the function is designed to handle non-standard input formats that simple casting cannot resolve, it performs validation checks [3][4]. For example, if the input string is too short for a given formatting field (e.g., expecting two digits but receiving one), the function will return an error [1]. 3. Special Options: - Default Behavior: By default, the function is somewhat liberal regarding separators and whitespace, often skipping them unless the FX (Fixed Format) modifier is used [3][5]. - FX Modifier: If FX is specified, the formatting becomes strictly positional, and the function will reject the input if it contains extra characters, unexpected separators, or does not match the template character-for-character [3][5]. 4. Practical Implications: Because this error occurs during type coercion, it will cause the current transaction to enter an aborted state if it occurs within a transaction block [2]. To handle expected conversion failures without aborting the entire transaction, you can use an EXCEPTION WHEN invalid_datetime_format clause inside a PL/pgSQL function [2]. Because to_timestamp is intended for non-standard formats, official documentation emphasizes that for most standard date/time formats, direct casting (e.g., source_string::timestamp) is preferred, more robust, and easier to use [3][5].

Store startedAt as ISO timestamp instead of locale-formatted string.
The watchdog query at lines 1685-1691 assumes non-ISO startedAt values match 'FMMM/FMDD/YYYY, FMHH12:MI:SS AM' (US format), but all instances write using new Date().toLocaleString(), which varies by locale (e.g., German: 15.6.2024, 14:30:45, French: 15/06/2024 14:30:45, UK: 15/06/2024, 14:30:45). When a locale-variant timestamp is encountered, PostgreSQL's to_timestamp() raises an error, causing the entire query to fail and the watchdog to skip recovery silently. This breaks the recovery mechanism for runs stuck in 'running' status.
Store startedAt as an ISO 8601 timestamp (or use the database's native timestamp type) and compare directly with a cutoff date in the query instead of parsing display strings.

Use a public-suffix-aware site boundary check.
The naive label-slicing approach fails for multi-label public suffixes, allowing unrelated sites to be treated identically. For example, shop.example.co.uk and login.attacker.co.uk both reduce to co.uk, bypassing the navigation guard and letting the agent navigate to an attacker-controlled site.
The function is used at two critical points:
- Line 533: validating navigation action URLs against the configured site
- Line 670: initializing the allowed domain from the initial page
A public-suffix-aware parser (e.g., tldts or psl) is needed, with exact-host matching as fallback for IP addresses. No such dependency currently exists.

Only stop repeated actions after confirming no page progress.
The counter is global per action signature and ignores page changes, so valid flows like clicking the same “Next” selector across pages or scrolling several times can fail on the third repeated signature even when progress is happening.

Handle CSS list selectors and no-match cases in fill-rate validation.
Line 480 always evaluates listSelector as XPath. For CSS list selectors this returns {}, and downstream undefined rates are retained, so the “drop empty fields” validation silently no-ops. Use a shared CSS/XPath evaluator and return zero rates when the list selector matches nothing.
