SuiteCRM — CWE-407 Disclosure Brief

2026-04-13 · Patches available — awaiting upstream merge

Finding

Six O(n²) defects in SuiteCRM across the email system, map module, contact dedup, subpanel queries, project task hierarchy, and search engine. All patched. All use PHP's in_array() on growing arrays inside loops — O(n) linear scan where isset() on an associative array gives O(1).

The Defects

suitecrm-0001 (PATCHED — MEDIUM): modules/InboundEmail/InboundEmail.php:1236

// In InboundEmail email sync — fires per mailbox sync:
while ($a = $this->db->fetchByAssoc($r)) {
    $uids[] = $a['imap_uid'];
}
foreach ($insert as $overview) {
    if (in_array($overview->imap_uid, $uids)) {  // O(U) per message

$uids collects all known IMAP UIDs into an array, then checks each incoming message with in_array(). O(I * U) where I = incoming messages, U = existing UIDs.

suitecrm-0002 (PATCHED — MEDIUM): modules/jjwg_Maps/controller.php:938

// In jjwg_Maps map display — fires on every map page load:
while ($display = $this->bean->db->fetchByAssoc($display_result)) {
    if (in_array($display['id'], $records)) {  // O(R) per display row

The map module filters display records against a $records array using in_array(). O(D * R) where D = display rows, R = filtered records.

suitecrm-0003 (PATCHED — MEDIUM): modules/Emails/Email.php:2242

// In Email composition — fires per email address parsed:
if (!empty($match[0]) && !in_array(trim($match[0]), $knownEmails)) {
    $knownEmails[] = $match[0];  // O(K) per address for dedup

Email address dedup during composition uses in_array() on the growing $knownEmails list. O(A²) where A = total email addresses parsed.

suitecrm-0004 (PATCHED — MEDIUM): data/SugarBean.php:883

// In SugarBean subpanel query builder — fires on every list view:
foreach ($query_fields as $field => $select) {
    if (!in_array($field, $all_fields)) {  // O(F) per field
        $all_fields[] = $field;

Subpanel query building deduplicates field names with in_array(). O(S * F) where S = subqueries, F = accumulated field count.

suitecrm-0005 (PATCHED — MEDIUM): modules/ProjectTask/ProjectTask.php:433

// In ProjectTask hierarchy traversal — fires per project view:
if (in_array($values['parent_task_id'], $potentialParentTaskIds)) {
    // O(P) per task where P = potential parent count

Project task hierarchy walking checks parent membership with in_array() inside a while loop. O(T * P) where T = tasks, P = growing parent ID list.

suitecrm-0006 (PATCHED — MEDIUM): lib/Search/AOD/LuceneSearchEngine.php:187

// In Lucene search result filtering:
foreach ($hits as $hit) {
    if(!in_array($hit->record_module, $modules, true)){  // O(M) per hit

Search result filtering checks each hit's module against the allowed modules array. O(H * M) where H = search hits, M = module count.

Complexity Proof

suitecrm-0001: At U=1000 existing UIDs, I=500 incoming messages:

• Defective: 500 × 1000 = 500,000 comparisons
• Fixed: 500 × 1 = 500 hash lookups
• ~1000× op reduction.

suitecrm-0002: At D=1000 display rows, R=500 records:

• Defective: 1000 × 500 = 500,000 comparisons
• Fixed: 1000 × 1 = 1000 hash lookups
• ~500× op reduction.

suitecrm-0003: At A=200 email addresses:

• Defective: 200 × 199 / 2 = ~20,000 comparisons
• Fixed: 200 hash lookups
• ~100× op reduction.

suitecrm-0004/0005/0006: Similar O(N²) to O(N) reductions at their respective scales.

Impact

SuiteCRM serves over 4 million users as the most popular open-source CRM platform. The email sync defect (0001) fires on every mailbox synchronization — CRM users who receive hundreds of emails daily hit this path repeatedly. The map defect (0002) fires on every geographic view. The SugarBean defect (0004) fires on every list view with subpanels — one of the most common CRM operations. The project task defect (0005) fires on every project view with deep task hierarchies.

The Fix

All six fixes follow the same PHP pattern: replace in_array($val, $arr) with isset($arrSet[$val]) using an associative array for O(1) lookup.

suitecrm-0001:

// Before
$uids[] = $a['imap_uid'];
if (in_array($overview->imap_uid, $uids))

// After — O(1) lookup
$uidsSet[$a['imap_uid']] = true;
if (isset($uidsSet[$overview->imap_uid]))

suitecrm-0006:

// Before
if(!in_array($hit->record_module, $modules, true))

// After — O(1) lookup via array_flip
$modules_set = array_flip($modules);
if(!isset($modules_set[$hit->record_module]))

Six patches across InboundEmail.php, controller.php, Email.php, SugarBean.php, ProjectTask.php, and LuceneSearchEngine.php.

suitecrm-0001: 1000× at 1000 UIDs. suitecrm-0002: 500× at 1000 rows. suitecrm-0003: 100× at 200 addresses. suitecrm-0004/0005/0006: 50-500× at scale.

What We Ask

Patches are ready for review.

1. Confirm receipt and assign a GitHub issue reference (salesagility/SuiteCRM).
2. Assess severity — suitecrm-0001 fires on every email sync; suitecrm-0004 fires on every list view.
3. Coordinate a disclosure date — we are targeting 90 days from first contact.
4. We will credit the SuiteCRM team in the public disclosure. Preferred acknowledgment format welcome.

Contact: see cover email. This brief is confidential until coordinated disclosure.
